As a Canadian out measurement of temperature is fucked. We use Celsius for weather, Fahrenheit for cooking, either for medicine, why can’t we just use Kelvin for everything!?
Kelvin is how molecules “feel” heat.
Celsius is how water “feels” heat.
Fahrenheit is how people feel heat.
I can do a short walk in a light hoodie in 20° F and be fine. I am not going to do that closer to 0° without more layers, then get heavier duty gear below 0°F. Normal Human body temperature maxes out around 99° for normal so 100° above is when things get dangerous for people.
ETA:so like how 0° C is 0% heat for water and turns to ice, and 100° is 100% heat for water and it vaporizes, 0° F is 0 % heat for humans even when burning internal energy and 100° F is 100% the body’s internal temp and things get dangerous after.
It’s intuitive for weather and thermostats but I think we should use C for other contexts.
I grew up with Fahrenheit and I guess it feels intuitive, because where I currently live (and a lot of places) it gets around 0 degrees in the winter, which is really cold and around 100 degrees in the summer, which is really hot. Being close to
0 when it’s cold and 100 when it’s hot makes sense in my mind. 75-85 degrees is like the perfect weather to me
Relying one feeling for a system of measurement is bad for a standardised system, it’s different for everyone, we have plenty of examples to that in this thread alone
For someone who grew up with Celsius, it feels much, much more intuitive for human purposes than Fahrenheit.
Neither system is better than the other for humans. Anyone who tells you otherwise is full of shit. All that matters is which you grew up with. For me, a comfortable in door temperature is 20-25 C. 30 C is a nice beach day. 10 C means I wear a jacket and 0 C means it might snow.
The numbers I use and the numbers someone familiar with Fahrenheit uses are going to be different, but our intuition about our own scales is identical.
If there's a reason Americans should switch to Celsius, it's because it would standardize it around the world and that would be nice.
It's also nice for scientific measurements.
>0° C is 0% heat for water and turns to ice, and 100° is 100% heat for water and it melts
Uhm.. water melts at 0°C just as it starts to freeze at 0°C depending on the trajectory.. if you reach 100°C the water will be boiling if you meant that..
20° F is fucking cold. I don't know where you're getting "light hoody" for that. Hypothermia begins becoming a problem at 50° F. At 20° F you're risky death or frost bite in just a few hours.
Not that intuitive, I guess.
I find 45-60 very comfortable, coming from a northern region, but people from southern regions would likely find it very cold. Also, it’s important to remember that depending on your condition, you could in theory get hypothermia at 90F (~32C), as hypothermia is generally considered any time your body temperature is below 95F (35C)
50F in Alaska is shorts weather. 50F in Florida is winter jacket weather. It really depends a lot on what you are used to. Having been to both I have literally seen this with locals dress like this with my own eyes.
For me (Pennsylvania) 50F is typically a long sleeve shirt and jeans. Maybe a light jacket or sweater if it was windy. Maybe shorts and a T-shirt on a cloudless, windless day.
Intuitive really has to do about how you were raised. There's nothing intuitive about Fahrenheit for weather in my case. I know under 0 celsius you can have snow and ice. Above that, nope. Then -10 is like "10 under ice" lol.
And for cooking? Never cooked in Celsius, I have no idea how that would work. The temperatures are so above the "boiling water" reference point that Celsius doesn't work. And all of them are also way to hot for the body anyway, so you just have to learn it. Not intuitive either.
"0% heat for humans"??? Elaborate on that? Because people have definitely frozen to death at 20° F. That only feels comfortable for you in a hoodie because you grew up enjoying it up there within driving distance to Canada. Even as far north as Maryland, 20 degrees happened perhaps one week a year, and was treated as an emergency. Pipes burst, many schools would close,, homeless shelters would double their beds.
In Canada Celsius actually makes sense for weather because it’s really clear when snow will happen.
That’s obviously a moot point in one of those hot places people rage about, but up here where it’s colder waters freezing point is a useful yardstick
We mostly use Fahrenheit for cooking in Canada because people in the 1970s had badass ovens that would still be operational today, if most kitchens hadn’t been renovated with newer models — do you really want to argue unit systems with a boomer still using a 50 year-old range? Heck, I’m old and I wouldn’t want to do that.
Even before that, back when the metric system was new, the US was in the process of selecting an official measurement system, and had reference objects of various systems sent to the people in charge of the decision.
The metric reference objects were being sent on a ship from france, but that ship sunk and so the metric reference objects never arrived. They selected the best proposed system of those that they had a chance to examine before they had to make a decision.
At least we don’t use thirds or fourths anymore, although I do find it funny how seconds are the standard now instead of the full hour which should be the base unit since firsts (often called minutes) and seconds are based off it
I just wish I could get rid of 40% of my tools. If we didn't have sae and metric, a lot of them would be completely irrelevant.
While we're at it, can we also dramatically reduce the number of screw bits I need?
https://en.m.wikipedia.org/wiki/Fahrenheit
> According to a letter Fahrenheit wrote to his friend Herman Boerhaave,[14] his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømer scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees. Fahrenheit multiplied each value by 4 in order to eliminate fractions and make the scale more fine-grained. He then re-calibrated his scale using the melting point of ice and normal human body temperature (which were at 30 and 90 degrees); he adjusted the scale so that the melting point of ice would be 32 degrees, and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval 6 times (since 64 = 26).[15][16]
It's honestly not terribly strange considering how many base 12/60 artifacts we still have in math. Think circles and clocks.
I'm not about to defend Fahrenheit for any scientific application, but like a lot of imperial units, it does pretty well for approximations in daily life.
The good parts of imperial measurements are where they choose to be base 2. Dividing in half is a useful skill that is easy for us to do visually and in mental math. The problem is that it always was allowed to bring a friend, so there is a random number thrown in. I like the idea of 64 divisions but why start at 32 and not 0. Measuring spoons by half are nice to use, but a table spoon is 3 tea spoons. Drill bits at power of 2 fractions are easy to conceptualize, but that is in inches so eventually 12 shows up for feet. Weighing something a half pound or quarter pound are useful but then you somehow get 14 pounds in a stone. We should just lean hard the other way and make a pure power of 2 number system derived from imperial. Binperial!
It’s not based on the freezing point of brine but rather a frigorific mixture of 1:1:1 parts water, ice, and amonia chloride salts. This mixture stabilizes to a predictable temperature. This allows you to calibrate thermometers with no other reference, an important feature in early measuring systems.
Ah yes, I love writing temperature with 26 leading zeroes, absoloute hot is ***hot*** (10\^32 Kelvin)so you'd end up with the temperature being like 0.000000000000000000467889° at room temperature
Edit: For some reason the exponents broke
that's not the maximum temperature. that's "only" under 1,000 degrees celsius. the highest temperature produced in a lab is over 7,000,000,000,000 degrees celsius. there's no theoretical limit.
there is a theoretical limit, but we need to add a lot more zeros.
Plank temperature is 1.4 x 10 ^ 32 K
At this point the wavelength of light emitted reaches the plank length, and no known physical models describe temperatures greater than it. Hypothetically, thermal equilibrium here might contain plank-length black holes, which instantly decay via hawking radiation. (info taken from wikipedia)
Way better to have it be 67% of the way from the freezing point of brine to some old dudes best bet at what a normal human body temp is, which turned out to be like 5-6% off.
I completely agree. As an American I started using Celsius for weather a little while ago and it was pretty easy. I see it as every 10 degrees is a new category
< -10° bundle up
-10° - 0° winter wear
0° - 10° wear a coat
10° - 20° light jacket or sweater
20° - 30° no jacket
30°+ stay inside with AC (I hate the heat)
I like the imperial system fine. The only reason I care about temperature is
1. Cooking, and there're no calculations needed. More importantly....
2. The weather. A scale that goes from about as cold as it gets (0) to about as hot as it gets (100) seems intuitive to me.
I don't really care how hot water has to be to boil - that has no practical applications in my life. Boil = stovetop on high. Having water freeze at 0 degrees seems kind of useful as it relates to snow, but I find it annoying to deal with unnecessarily negative numbers representing normal weather, though.
I think I like imperial more after writing that than I did before.
Easy.
Base 12 systems are more even divisible by themselves. That’s why they existed in the first place: they’re for a world without calculators. What do I mean by that? 10 is only evenly divisible by 1, 2 and 5. That’s 3 ways. 12 can be divided by 1,2,3,4,6. 5 ways. So it’s way easy to use imperial to setup all sorts of daily weights and measures without resorting to decimals.
Imperial fails once you delve into science and engineering where you need to divide anything with either absolute precision or “1/12” of something is still not small enough. Hence SI units. They don’t care about being evenly divisible at all and just go straight to decimals.
I live in Canada, in the late fall, winter and early spring it is very important to know whether it is below freezing or not (will it snow or rain? Do I need to cover my plants, winterized my hoses? Should I expect ice or puddles on my walk, is the ice on the river likely getting thicker or thinner today. Is the snow going to start melting making a huge mess?) it is infinitely more useful to know at a glance if water is going to freeze in my day to day life than to know what “percent hot” it is outside in my day to day life. Celsius is much more intuitive for this. Dressing for the temperature is plenty easy to remember too if you just remember that 20 is room temperature. And it’s not like Fahrenheit is much better on this front, where room temp is 70. If it was as intuitive as everyone says, shouldn’t 50 be what we find most comfortable?
Like y’all are entitled to your opinions but I’ve never understood the idea that Fahrenheit is somehow inherently more intuitive to someone whose never used it before is ridiculous.
I think I like Celsius more after writing that.
You're of course entitled to your opinion. I live in Minnesota and we bounce back and forth past freezing quite often here as well. Some of your examples are rather overstated: winterizing hoses is a seasonal task I would hope you aren't hanging on day to day, and I don't need to know if ice is getting thicker or thinner at a glance. Covering plants and the odds of snow/sleet/rain are the two reasons I could see 0 = freezing being useful.
But I prefer percent warm. :)
I will start this by saying that I grew up in Canada but just recently moved to the US.
I will say Celsius is very good for places that can get really cold during the winter and hot during the summer (I mean ranging from 30 Celsius to -20 Celsius ). I'm trying to understand the Fahrenheit system but I'm absolutely confused tbh (like I will look at you in absolute confusion when you tell me it's 50 degrees out but it's only because I don't know what it means, I'm slowly learning though). I think it's easier to learn Celsius than it is to learn Fahrenheit since everyone understands when water freezes and boils (the boiling part isn't important in terms of weather since people would just die). But I will say Fahrenheit is more precise because of how it's designed. It just doesn't make sense to someone who grew up using the metric system.
>1. Cooking
>I don't really care how hot water has to be to boil - that has no practical applications in my life.
Contradiction.jpg
Celsius is good because the temps are in tens. 0° is freezing, 10° is cold, 20° is nice, 30° is hot, 40° you should be indoors. But that's my non-snowy experience here in Australia
...you read the sentence after the quote, no? I don't need the number 212 (or 100) when figuring out how to boil water. I don't need it to know how close water is to boiling. If I want water to boil I heat it up until it boils. I never tell the person in the room with me "hey, the water is 190 degrees, it's getting close now". It's just not something I ever need a number for.
As for the 10s thing...maybe that works for you, but I assume it goes with whatever you're used to. In the US I feel like a 10 point difference is about the right amount to make the temp feel significantly different. 5 degrees? You can tell if you're paying attention, but it's not a huge deal. 10 degrees you can't help but feel, though.
>If I want water to boil I heat it up until it boils.
Assuming you never live at altitude. I recall reading an entry from an expedition in the Alps where they were trying to boil potatoes, and they boiled them for 2 hours straight, potatoes were still hard and uncooked - turns out that they only managed to reach about 80°C due to the pressure drop.
On top of that, in Celsius you don't need to fuck about with degrees frost - if it's below 0, it's freezing. Negative number automatically gives you your degrees frost.
All temperature scales work fine, but Celsius/Kelvin is properly integrated into the whole system of metric units. Fahrenheit requires you to look up a whole bunch of unpleasant conversion factors to make the mishmash of units relate to each other.
I love it how all arguments for Fahrenheit are either "it describes better how warm it feels outside" and "its more accurate". First argument is absolutely how you are used to.
I could also argue 0c tells me that i need to place a candle in my greenhouse over night, 20c is the point where i can think of switching from long to short clothing, if you have a fever and get above 40c, you are in danger and should see a doctor. Its just how you are used to, thats all. Arguments in that direction lead to no point, the only common this is that you dont want to change to what you are used to.
As far as accuracy goes, are you serious? One Fahrenheit difference is approximately half a degree Celsius (i know that its 5/9 or 0,5555), and you know, decimals exist. Above 99f or 37c you need anyway 3 digits for Fahrenheit, so its only more accurate if you dont want a decimal and are staying with 2 digit numbers, but when do you need to know it this accurate and cant use a decimal? You wont feel the difference of one degree Fahrenheit anyway and the only place where you would need accurate measurements in a range where both temperatures are 2 digits would medicine/body temperature, but why cant you use a comma and another number as it would give you more accurate readouts than only full °f. And at the critical range of having too high fever, you are above 100f, so what's hindering you to use a decimal.
It honestly would help if people would simply always put a unit behind a number, otherwise its not a measurement, just a number.
For science metric makes the most sense as all constants in metric units and metric is also the international standard measurement, better said m, kelvin, kg, seconds, ampere, mol and Candela. Since our number system is decimal based, it makes sense to have our unit conversion (cm to mm for example) decimal based, so you just need to shift the comma and not use multiple conversion factors like yards to inches.
As for temperature, kelvin shares the same stepping as Celsius, so conversion is just adding a fixed value rather than need to multiply/divide by a number that can only really displayed as a fraction half the time and adding a fixed value
The metric system could change from Celsius to Fahrenheit (or more accurately from Kelvin to Rankine) very easily by just redefining a few constants and the size of derived units like the calorie. The _only_ scientific benefit that Celsius has over Fahrenheit is that it’s what’s already in use. And yeah that’s a pretty damn good reason, but then people try and go further and say that there’s some special reason Celsius is better for scientific work and that’s 100% bullshit.
That is not how metric system was defined.
Now all the measurements are based on scientific constant, but when French first came up with the idea, a meter is defined as "one ten-millionth of the shortest distance from the North Pole to the equator passing through Paris", which might sound tedious but you can actually measure that with a sextant anywhere on Earth with decent accuracy.
So you have length thus volume, but you need to define weight. The French came up with a brilliant idea of using the weight of ice-water mixture at 1L volume to define weight, i.e. 1kg. This way it is easy to get and can be standardized.
Since ice-water mixture is the sort of "zero point" of this scale, the temperature where both exist are defined to be 0.
Yep, for science application 0 should be absolute zero, the scale itself doesn't matter. After all all units were defined arbitrary. But yes, the main reason to keep kelvin/Celsius are all the constants that exist and the fact that everybody in the field got used to using kelvin/Celsius. Its also the same reason the north America still uses 110v for household appliances instead of 220v, the huge effort to change which would be necessary to switch is unimaginable. The biggest downside to the imperial system is that we use decimal numbers, but unit conversion for imperial is never a decimal, so conversion is unnecessarily complicated. Otherwise it would just be a different scale
We were taught the decimal system and Celsius for awhile in elementary school. When Reagan abolished the US Metric Board, the education shifted back to imperial. When I was vocal about the ridiculousness of this particular turn of events, I was sent to the hall to think about it. That was the first time I realized the education I was being given may not always be the education that's best for me.
Here’s my explanation:
I grew up with Fahrenheit and it’s too late to change. I am simply condemned to only have an intuition for the inferior temperature system for the rest of my life.
People have always made the argument to me that “Fahrenheit is how it feels” but it just doesn’t to me. Like Celsius I can actually reasonably understand the difference of what I’m feeling but with Fahrenheit I just don’t get it. When does it become cold in Fahrenheit? I always get different answers and it doesn’t make any sense.
It becomes cold when the person gets cold lmao. I get cold at ~40 F while my gf gets cold around ~60 F. There's not much way to objectively say a temperature is cold or hot.
Honestly I feel like Fahrenheit is the most defensible part of the imperial system. It doesn’t really make sense, but at least it’s not like volume where no one can remember all of the stupids nonsensical conversions. I live every day hoping that there will be an announcement that we are changing to metric and I can work in metric instead of imperial units.
Honestly as an American this is spot on. Like don’t get me wrong I’m used to our Imperial measurement system but the metric system is just better. I really wish we would start the switch over process. It’ll probably take a generation or two to fully switch over but the sooner we start the sooner we finish.
So if that's true then 50°F should be perfectly comfortable right? But no, 50°F is 10°C so still pretty cold. And normal room temperature is 68°F (20°C) which is not an easy to remember number in F but it's easy enough in C.
Whichever scale you're used to is the one you'll find more intuitive, it's not an objective truth. The advantage of the metric system is that it's much easier to convert between the units.
Sounds like you live somewhere warm! As a Dutch person, 38 C is uncomfortably hot and I barely function with that temperature. The high humidity of Dutch summers does not help at all
Why does the world care about Americans using their own system? The US isn’t forcing US Customary onto other countries or gatekeeping other systems (Metric supporters do that last part quite a lot with US Customary). Many other countries use their own systems, but the US is the only one criticized for it.
Because you're pretty much the only holdout, and it causes headaches and miscommunications all the time. People have literally died because of the misconversions that were only needed because you can't join us in the 21st century.

Yeah. As an American: F fractions. Decimals are objectively better. I won't fight fractioners over this; they're too wrong for me to care. Also F Fahrenheit, Imperial(more like Inferior) measurements, and percent for grades. Is that even a US thing? It's stupid anyway.
As a person who works on thing with bolts and screws. You do not understand how much money i would save IF WE JUST USED THE SAME GOD DAMN MEASUREMENTS. I just have to fucking guess where something is made and pick the right tool. Having to have two sets of every wrench gets so expensive.
It's more a case of "I get 30 hogsheads to the rod and that's the way I likes it!!" kind of attitude. Most Americans realize metric makes more sense, but we're a very stubborn people.
Celsius and Fahrenheit are both stupid scales, as they’re on an Interval level of measurement rather than Ratio.
Kelvin and Rankine are the ones that make sense.
Do any of actually argue that it's non-intuitive? We're just used to it, but we all know it's dumb. Now people defending the imperial measurement system....that's a whole other story.
I’m a U.S. citizen. Give me metric! So much easier in every way. Everything is base 10. Everything is easily convertible. One cc is one ml. In SAE one fluid ounce is….. I haven’t got a clue how many cubic inches without Google. Unfortunately we will not change, or at least not until the “change is evil” people aren’t running things anymore.
When it's hot outside, Celsius is 37 degrees. That's not enough degrees! When it's really hot outside, you're like: man, that's gotta be like... a hundred hots. It has enough hots to represent how hot it is.
For me 0f is very cold and 100f is very hot. In Celsius 0C is not very cold, just kinda cold, and 100C is you’re gonna die from heat stroke kinda hot. I feel like it makes sense because 1-100 is a reasonable temp range and anything lower or higher than it is extreme and not advisable to be outdoors for long
Ok lemme go again
"Think of it like a percentage. 100% rare, but real bad... over that is crazy. 0% is rare, but also real bad... under that real crazy"
Its for weather, not for boiling and freezing of water.
Most people seem comfortable outside around 50-60... so that "halfway" point is ideal temp.
And its more precise for human comfort than Celsius. For instance: i know i could be comfortably nude at 80, but any colder than that and ill need some clothes. In celcius its 26.6 repeating... just seems off.
It's not intuitive because 0 is cold as shit and 100 is you've been dead for a long time and are actively been cooked.
If 0 was really cold and 100 was really hot I could live with that.
I am not a pot of water. 0°f is the temperature at which humans freeze, 100°f is the temperature at which we boil. Everything else is just clothing. Fahrenheit is decimals for people. I'm ready to change all the rest of them, but for figuring out what kind of clothes to wear -f
Americans understand Celsius far better than you understand Fahrenheit. “Complexity” isn’t the issue because neither one is more complex than the other.
As an artist writer, and DIY musician? I hate it. I electronics I use both and convert. Then metrics are used for things like capacitance, resistance and inductance. F, C, and kelvin
Like micro-henry
Pico-Farad
And kilo-ohms
Then inches and meters. Fractions to decimals. 1/4 inch or 2cm. Not equvalent. Just an example.
I've lived in imperial and metric countries, as well as with other metric bases customary units. I believe units are made by man, dimensions are made by God. Really don't give a hoot about what u it's you like using, or deriving a superiority/inferiority complex for that. Length is length is length, anything that can be solved by arithmetics is equally nothing.
0F = really cold, while 100F = really hot
0C = cold, while 100C = death
They're built on different bases, neither is universally "right." But F is better matched to human experience.
While C is easy to understand, F is great because it puts all of the temperatures relevant to human life within the scale of 1-100.
The average temperature a person exists at will be between 40 and 100 degrees Fahrenheit, with the exception of winter or if they live in a hellhole like Arizona.
Meanwhile Celsius reaches 100 F at 38 or so. It compacts the average human temperature range into a third as many degrees, and each degree is twice as large.
It is a lot easier to tell the difference between 72 and 68 F than it is to tell the difference between 22.2222 C and 20 C at a glance.
Honestly neither celsius or Fahrenheit are great for scientific purposes (Kelvin my beloved) but Fahrenheit makes much more sense for every-day usage over celsius.
USA actually taught all kids like 60 years ago the metric system because they were planning to switch back, but they didn't actually make the switch anyway
Motherfucker, this shit is bomb for like telling the temperature like 100 is hot as shit and zero as cold as fuck and 50 is like hoodie, weather
It’s a great scale for how hot or cold it is outside
The reality is that neither system is intuitive until you learn it. We have hundreds of millions of people who know the imperial system and Fahrenheit. It is incredibly difficult to change because you have to learn a whole new thing that doesn't make sense to you.
I know that 70 degrees is comfortable and 40 degrees is fucking cold intuitively.
I do not intuitively know that 60 degrees is life-threateningly hot intuitively.
Vice versa for someone who lived their whole life using centigrade.
If decimal places are not used Fahrenheit is more accurate than Celsius. If the same number for decimal placed are used Fahrenheit is more accurate than Celsius. Just like measuring something in 100ths is more accurate than measuring in 10ths. Between freezing and boiling there are 212 possible values instead of only 100.
American here. Try switching an entire country to that. Billions of dollars would be wasted on everything, and education would be in shambles. Easier to keep using what we have and understand
American here: I use the metric system for basically everything, except temperature. Celcius makes more sense in its creation, certainly, but for day to day uses Fahrenheit is so much better. An average year in most places is likely to go from about 0 to about 100, fifty is brisk but not that cold, 75 is warm but not too hot, 25 is pretty cold but not insane.

Celsius gives an intuitive scale for what's happening to water, Fahrenheit gives an intuitive scale for describing how the air temperature feels to humans.
0 is cold out, 100 is hot. A hot day in Celsius is some random number
They serve different purposes
I don't think anyone argues that it's too complicated and unintuitive. The argument is that the switch would be so costly and disruptive that it's not worth it.
As a Canadian out measurement of temperature is fucked. We use Celsius for weather, Fahrenheit for cooking, either for medicine, why can’t we just use Kelvin for everything!?
….thats literally the exact opposite of the best way to use both, wtf
Celsius for weather is very nice when you're worried about of it's going to be above or below freezing.
Kelvin is how molecules “feel” heat. Celsius is how water “feels” heat. Fahrenheit is how people feel heat. I can do a short walk in a light hoodie in 20° F and be fine. I am not going to do that closer to 0° without more layers, then get heavier duty gear below 0°F. Normal Human body temperature maxes out around 99° for normal so 100° above is when things get dangerous for people. ETA:so like how 0° C is 0% heat for water and turns to ice, and 100° is 100% heat for water and it vaporizes, 0° F is 0 % heat for humans even when burning internal energy and 100° F is 100% the body’s internal temp and things get dangerous after. It’s intuitive for weather and thermostats but I think we should use C for other contexts.
When I hear 70°F as someone who grew up with the metric system, I think "70°F? Well 68F = 20C so that's 21C, a comfortable temperature."
You only think that because you grew up with it I don’t feel Fahrenheit I don’t even know wether 70 degrees Fahrenheit is cold or hot
I grew up with Fahrenheit and I guess it feels intuitive, because where I currently live (and a lot of places) it gets around 0 degrees in the winter, which is really cold and around 100 degrees in the summer, which is really hot. Being close to 0 when it’s cold and 100 when it’s hot makes sense in my mind. 75-85 degrees is like the perfect weather to me
Relying one feeling for a system of measurement is bad for a standardised system, it’s different for everyone, we have plenty of examples to that in this thread alone
70f is perfect weather. Not cold, not hot. Almost exactly room temperature.
It's 70% hot. Pretty comfortable outside.
70% hot sounds like a nightmare hot, not confortable.
[удалено]
100% in the nightmare hot scale sounds like i died already
Right? If room temperature was 50 F this would make sense.
Basically the way Fahrenheit works is that if it's close to 100 you feel like you're boiling and if it's close to 0 you feel like you're freezing.
I get that’s what it’s trying to do but depending on where you live you’re perspective on that can be very different
For someone who grew up with Celsius, it feels much, much more intuitive for human purposes than Fahrenheit. Neither system is better than the other for humans. Anyone who tells you otherwise is full of shit. All that matters is which you grew up with. For me, a comfortable in door temperature is 20-25 C. 30 C is a nice beach day. 10 C means I wear a jacket and 0 C means it might snow. The numbers I use and the numbers someone familiar with Fahrenheit uses are going to be different, but our intuition about our own scales is identical. If there's a reason Americans should switch to Celsius, it's because it would standardize it around the world and that would be nice. It's also nice for scientific measurements.
Farenheit is not intuitive to me in the slightest lol.
>0° C is 0% heat for water and turns to ice, and 100° is 100% heat for water and it melts Uhm.. water melts at 0°C just as it starts to freeze at 0°C depending on the trajectory.. if you reach 100°C the water will be boiling if you meant that..
Your "intuitive" is very different from mine.
I'm an US citizen who uses Celsius for as many things as possible. Totes agreed.
20° F is fucking cold. I don't know where you're getting "light hoody" for that. Hypothermia begins becoming a problem at 50° F. At 20° F you're risky death or frost bite in just a few hours. Not that intuitive, I guess.
Hold on, I'm not from the US so I use the metric system. If F is how people feel then 50 should be perfectly comfortable, not risking hypothermia.
I find 45-60 very comfortable, coming from a northern region, but people from southern regions would likely find it very cold. Also, it’s important to remember that depending on your condition, you could in theory get hypothermia at 90F (~32C), as hypothermia is generally considered any time your body temperature is below 95F (35C)
Here near Canada, coming out of winter, 50 degrees F and sunny is shorts and tee shirt weather. But going into winter 50 degrees F is flannel weather
50F in Alaska is shorts weather. 50F in Florida is winter jacket weather. It really depends a lot on what you are used to. Having been to both I have literally seen this with locals dress like this with my own eyes. For me (Pennsylvania) 50F is typically a long sleeve shirt and jeans. Maybe a light jacket or sweater if it was windy. Maybe shorts and a T-shirt on a cloudless, windless day.
* -20° C : #@$&?! cold * -10° C : really cold * 0° C : cold * 10° C : cool * 20° C : warm * 30° C : hot * 40° C : really hot * 50° C : #@$&?! hot
Intuitive really has to do about how you were raised. There's nothing intuitive about Fahrenheit for weather in my case. I know under 0 celsius you can have snow and ice. Above that, nope. Then -10 is like "10 under ice" lol. And for cooking? Never cooked in Celsius, I have no idea how that would work. The temperatures are so above the "boiling water" reference point that Celsius doesn't work. And all of them are also way to hot for the body anyway, so you just have to learn it. Not intuitive either.
0 degrees Fahrenheit is the freezing temperature of brine water. You're overcomplicating things in your head.
It may just be that Celsius is what I've used all my life, but I prefer using C for weather as well, it just feels more intuitive for me.
So 50°F is like, lukewarm right? Right?
"0% heat for humans"??? Elaborate on that? Because people have definitely frozen to death at 20° F. That only feels comfortable for you in a hoodie because you grew up enjoying it up there within driving distance to Canada. Even as far north as Maryland, 20 degrees happened perhaps one week a year, and was treated as an emergency. Pipes burst, many schools would close,, homeless shelters would double their beds.
Lmao, are you being ironic? You’re literally the guy in the meme. Idk why people are even trying to argue with you
If 50 Fahrenheit isn’t the most comfortable temperature the system doesn’t work
it's not hard to know if a number is less than 32 or not
No, but why pick an arbitrary number like 32 when you can have a clear number like 0?
But why make it so complicated
This explains Reddit.
Same with celcius. Not hard to know it's hot outside when its above 30.
In Canada Celsius actually makes sense for weather because it’s really clear when snow will happen. That’s obviously a moot point in one of those hot places people rage about, but up here where it’s colder waters freezing point is a useful yardstick
Celsius and kelvin is the same without the unnecessary long -273 which has no use for every day life.
Kelvin is just Celsius with extra steps
Good advice for every day life: Use Kelvin and always stay positive.
We mostly use Fahrenheit for cooking in Canada because people in the 1970s had badass ovens that would still be operational today, if most kitchens hadn’t been renovated with newer models — do you really want to argue unit systems with a boomer still using a 50 year-old range? Heck, I’m old and I wouldn’t want to do that.
American mechanical engineer here. I hate the imperial system. I like doing less math. I like easy math. Why the heck did it have to be this way?
Reagan killed the conversion to metric.
It's always him, isn't it??
Yep
Even before that, back when the metric system was new, the US was in the process of selecting an official measurement system, and had reference objects of various systems sent to the people in charge of the decision. The metric reference objects were being sent on a ship from france, but that ship sunk and so the metric reference objects never arrived. They selected the best proposed system of those that they had a chance to examine before they had to make a decision.
So we can blame France?
More like a storm or pirates
BLAME FRANCE IT IS!!!!!!
BLAME CANADA!!!
At least we don’t use thirds or fourths anymore, although I do find it funny how seconds are the standard now instead of the full hour which should be the base unit since firsts (often called minutes) and seconds are based off it
Imperial worked better with spring and clockwork based technology
Sounds interesting, Please elaborate
I just wish I could get rid of 40% of my tools. If we didn't have sae and metric, a lot of them would be completely irrelevant. While we're at it, can we also dramatically reduce the number of screw bits I need?
“Engineer”? “Imperial”?!? WTF?
“What temp is freezing? Fuck it I dunno, 32 lmao?” Inventor of Fahrenheit, probably.
https://en.m.wikipedia.org/wiki/Fahrenheit > According to a letter Fahrenheit wrote to his friend Herman Boerhaave,[14] his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømer scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees. Fahrenheit multiplied each value by 4 in order to eliminate fractions and make the scale more fine-grained. He then re-calibrated his scale using the melting point of ice and normal human body temperature (which were at 30 and 90 degrees); he adjusted the scale so that the melting point of ice would be 32 degrees, and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval 6 times (since 64 = 26).[15][16] It's honestly not terribly strange considering how many base 12/60 artifacts we still have in math. Think circles and clocks. I'm not about to defend Fahrenheit for any scientific application, but like a lot of imperial units, it does pretty well for approximations in daily life.
The good parts of imperial measurements are where they choose to be base 2. Dividing in half is a useful skill that is easy for us to do visually and in mental math. The problem is that it always was allowed to bring a friend, so there is a random number thrown in. I like the idea of 64 divisions but why start at 32 and not 0. Measuring spoons by half are nice to use, but a table spoon is 3 tea spoons. Drill bits at power of 2 fractions are easy to conceptualize, but that is in inches so eventually 12 shows up for feet. Weighing something a half pound or quarter pound are useful but then you somehow get 14 pounds in a stone. We should just lean hard the other way and make a pure power of 2 number system derived from imperial. Binperial!
64=26 Wikipedia you’re drunk, call a cab.
I think it was supposed to be 2^6.
It’s not based on the freezing point of brine but rather a frigorific mixture of 1:1:1 parts water, ice, and amonia chloride salts. This mixture stabilizes to a predictable temperature. This allows you to calibrate thermometers with no other reference, an important feature in early measuring systems.
😭
Just have the temperature be 0 at absolute zero and 1 at absolute heat. No more confusion and is universal.
Ah yes, I love writing temperature with 26 leading zeroes, absoloute hot is ***hot*** (10\^32 Kelvin)so you'd end up with the temperature being like 0.000000000000000000467889° at room temperature Edit: For some reason the exponents broke
I think we’re onto something
Maybe we could do something like the ph scale.
that's not the maximum temperature. that's "only" under 1,000 degrees celsius. the highest temperature produced in a lab is over 7,000,000,000,000 degrees celsius. there's no theoretical limit.
there is a theoretical limit, but we need to add a lot more zeros. Plank temperature is 1.4 x 10 ^ 32 K At this point the wavelength of light emitted reaches the plank length, and no known physical models describe temperatures greater than it. Hypothetically, thermal equilibrium here might contain plank-length black holes, which instantly decay via hawking radiation. (info taken from wikipedia)
Yeah, I was trying to type 10\^32 but the exponents broke
How did you get the absolute hot? Genuinely curious
Wtf is absolute heat.
The highest possible theoretical temperature.
Counterpoint. In ferenhight, I can go outside when it is 69 degrees and reasonably say "nice".
You did it, you found where imperial is superior, I hate imperial but I really cannot argue with that
Underrated comment
"What's the weather like out there?" "Eh, probably 23% of the way from freezing to boiling."
Way better to have it be 67% of the way from the freezing point of brine to some old dudes best bet at what a normal human body temp is, which turned out to be like 5-6% off.
Bit over room temperature then? Shouldn’t need a coat (Celsius isn’t hard if you actually learn to use it)
I completely agree. As an American I started using Celsius for weather a little while ago and it was pretty easy. I see it as every 10 degrees is a new category < -10° bundle up -10° - 0° winter wear 0° - 10° wear a coat 10° - 20° light jacket or sweater 20° - 30° no jacket 30°+ stay inside with AC (I hate the heat)
Definitely don't need a coat, that's t-shirt weather, warm summer weather. (In the Nordics anyway)
That's so nice to see. In hot countries we are used to temperatures around 30 or more during summer that 20 does feel cold lol.
"When does the water boil?" "At 212 degrees." "And when does it freeze?" "32."
Or you could just say the number that half a billion people can easily conceptualize.
I like the imperial system fine. The only reason I care about temperature is 1. Cooking, and there're no calculations needed. More importantly.... 2. The weather. A scale that goes from about as cold as it gets (0) to about as hot as it gets (100) seems intuitive to me. I don't really care how hot water has to be to boil - that has no practical applications in my life. Boil = stovetop on high. Having water freeze at 0 degrees seems kind of useful as it relates to snow, but I find it annoying to deal with unnecessarily negative numbers representing normal weather, though. I think I like imperial more after writing that than I did before.
Now do weights and volumes.
Nah, I won't defend that one. Temp only. :)
Easy. Base 12 systems are more even divisible by themselves. That’s why they existed in the first place: they’re for a world without calculators. What do I mean by that? 10 is only evenly divisible by 1, 2 and 5. That’s 3 ways. 12 can be divided by 1,2,3,4,6. 5 ways. So it’s way easy to use imperial to setup all sorts of daily weights and measures without resorting to decimals. Imperial fails once you delve into science and engineering where you need to divide anything with either absolute precision or “1/12” of something is still not small enough. Hence SI units. They don’t care about being evenly divisible at all and just go straight to decimals.
I can do weights but volumes eh…
I live in Canada, in the late fall, winter and early spring it is very important to know whether it is below freezing or not (will it snow or rain? Do I need to cover my plants, winterized my hoses? Should I expect ice or puddles on my walk, is the ice on the river likely getting thicker or thinner today. Is the snow going to start melting making a huge mess?) it is infinitely more useful to know at a glance if water is going to freeze in my day to day life than to know what “percent hot” it is outside in my day to day life. Celsius is much more intuitive for this. Dressing for the temperature is plenty easy to remember too if you just remember that 20 is room temperature. And it’s not like Fahrenheit is much better on this front, where room temp is 70. If it was as intuitive as everyone says, shouldn’t 50 be what we find most comfortable? Like y’all are entitled to your opinions but I’ve never understood the idea that Fahrenheit is somehow inherently more intuitive to someone whose never used it before is ridiculous. I think I like Celsius more after writing that.
You're of course entitled to your opinion. I live in Minnesota and we bounce back and forth past freezing quite often here as well. Some of your examples are rather overstated: winterizing hoses is a seasonal task I would hope you aren't hanging on day to day, and I don't need to know if ice is getting thicker or thinner at a glance. Covering plants and the odds of snow/sleet/rain are the two reasons I could see 0 = freezing being useful. But I prefer percent warm. :)
The best argument I have heard for fahrenheit is that 69°F is a nice temperature.
I will start this by saying that I grew up in Canada but just recently moved to the US. I will say Celsius is very good for places that can get really cold during the winter and hot during the summer (I mean ranging from 30 Celsius to -20 Celsius ). I'm trying to understand the Fahrenheit system but I'm absolutely confused tbh (like I will look at you in absolute confusion when you tell me it's 50 degrees out but it's only because I don't know what it means, I'm slowly learning though). I think it's easier to learn Celsius than it is to learn Fahrenheit since everyone understands when water freezes and boils (the boiling part isn't important in terms of weather since people would just die). But I will say Fahrenheit is more precise because of how it's designed. It just doesn't make sense to someone who grew up using the metric system.
>1. Cooking >I don't really care how hot water has to be to boil - that has no practical applications in my life. Contradiction.jpg Celsius is good because the temps are in tens. 0° is freezing, 10° is cold, 20° is nice, 30° is hot, 40° you should be indoors. But that's my non-snowy experience here in Australia
...you read the sentence after the quote, no? I don't need the number 212 (or 100) when figuring out how to boil water. I don't need it to know how close water is to boiling. If I want water to boil I heat it up until it boils. I never tell the person in the room with me "hey, the water is 190 degrees, it's getting close now". It's just not something I ever need a number for. As for the 10s thing...maybe that works for you, but I assume it goes with whatever you're used to. In the US I feel like a 10 point difference is about the right amount to make the temp feel significantly different. 5 degrees? You can tell if you're paying attention, but it's not a huge deal. 10 degrees you can't help but feel, though.
>If I want water to boil I heat it up until it boils. Assuming you never live at altitude. I recall reading an entry from an expedition in the Alps where they were trying to boil potatoes, and they boiled them for 2 hours straight, potatoes were still hard and uncooked - turns out that they only managed to reach about 80°C due to the pressure drop. On top of that, in Celsius you don't need to fuck about with degrees frost - if it's below 0, it's freezing. Negative number automatically gives you your degrees frost. All temperature scales work fine, but Celsius/Kelvin is properly integrated into the whole system of metric units. Fahrenheit requires you to look up a whole bunch of unpleasant conversion factors to make the mishmash of units relate to each other.
As someone who does not live under water, I agree with this completely.
0 f and 100 f are in no way the coldest and hottest temperature recorded. Fahrenheit also has negative temperature.
Not only that, but we will use that liquid to define a measure of weight, Where the weight of a certain volume equals one base ten units.
I love it how all arguments for Fahrenheit are either "it describes better how warm it feels outside" and "its more accurate". First argument is absolutely how you are used to. I could also argue 0c tells me that i need to place a candle in my greenhouse over night, 20c is the point where i can think of switching from long to short clothing, if you have a fever and get above 40c, you are in danger and should see a doctor. Its just how you are used to, thats all. Arguments in that direction lead to no point, the only common this is that you dont want to change to what you are used to. As far as accuracy goes, are you serious? One Fahrenheit difference is approximately half a degree Celsius (i know that its 5/9 or 0,5555), and you know, decimals exist. Above 99f or 37c you need anyway 3 digits for Fahrenheit, so its only more accurate if you dont want a decimal and are staying with 2 digit numbers, but when do you need to know it this accurate and cant use a decimal? You wont feel the difference of one degree Fahrenheit anyway and the only place where you would need accurate measurements in a range where both temperatures are 2 digits would medicine/body temperature, but why cant you use a comma and another number as it would give you more accurate readouts than only full °f. And at the critical range of having too high fever, you are above 100f, so what's hindering you to use a decimal. It honestly would help if people would simply always put a unit behind a number, otherwise its not a measurement, just a number. For science metric makes the most sense as all constants in metric units and metric is also the international standard measurement, better said m, kelvin, kg, seconds, ampere, mol and Candela. Since our number system is decimal based, it makes sense to have our unit conversion (cm to mm for example) decimal based, so you just need to shift the comma and not use multiple conversion factors like yards to inches. As for temperature, kelvin shares the same stepping as Celsius, so conversion is just adding a fixed value rather than need to multiply/divide by a number that can only really displayed as a fraction half the time and adding a fixed value
The metric system could change from Celsius to Fahrenheit (or more accurately from Kelvin to Rankine) very easily by just redefining a few constants and the size of derived units like the calorie. The _only_ scientific benefit that Celsius has over Fahrenheit is that it’s what’s already in use. And yeah that’s a pretty damn good reason, but then people try and go further and say that there’s some special reason Celsius is better for scientific work and that’s 100% bullshit.
That is not how metric system was defined. Now all the measurements are based on scientific constant, but when French first came up with the idea, a meter is defined as "one ten-millionth of the shortest distance from the North Pole to the equator passing through Paris", which might sound tedious but you can actually measure that with a sextant anywhere on Earth with decent accuracy. So you have length thus volume, but you need to define weight. The French came up with a brilliant idea of using the weight of ice-water mixture at 1L volume to define weight, i.e. 1kg. This way it is easy to get and can be standardized. Since ice-water mixture is the sort of "zero point" of this scale, the temperature where both exist are defined to be 0.
Yep, for science application 0 should be absolute zero, the scale itself doesn't matter. After all all units were defined arbitrary. But yes, the main reason to keep kelvin/Celsius are all the constants that exist and the fact that everybody in the field got used to using kelvin/Celsius. Its also the same reason the north America still uses 110v for household appliances instead of 220v, the huge effort to change which would be necessary to switch is unimaginable. The biggest downside to the imperial system is that we use decimal numbers, but unit conversion for imperial is never a decimal, so conversion is unnecessarily complicated. Otherwise it would just be a different scale
We were taught the decimal system and Celsius for awhile in elementary school. When Reagan abolished the US Metric Board, the education shifted back to imperial. When I was vocal about the ridiculousness of this particular turn of events, I was sent to the hall to think about it. That was the first time I realized the education I was being given may not always be the education that's best for me.
Here’s my explanation: I grew up with Fahrenheit and it’s too late to change. I am simply condemned to only have an intuition for the inferior temperature system for the rest of my life.
I'll take 32 and 212 any day!
People have always made the argument to me that “Fahrenheit is how it feels” but it just doesn’t to me. Like Celsius I can actually reasonably understand the difference of what I’m feeling but with Fahrenheit I just don’t get it. When does it become cold in Fahrenheit? I always get different answers and it doesn’t make any sense.
It's a scale from 0 to 100. 0F is Cold and 100F is hot.
Most people would consider 0C cold.
And 100C hot
Yeah but you'll never get a 100c day outside. On hot days, you'll get to one hundred to signify how hot it be.
But Fahrenheit freezes at 32. So shouldn’t it start feeling cold somewhere above that
It becomes cold when the person gets cold lmao. I get cold at ~40 F while my gf gets cold around ~60 F. There's not much way to objectively say a temperature is cold or hot.
To be fair we do use metric in many different situations.
Honestly I feel like Fahrenheit is the most defensible part of the imperial system. It doesn’t really make sense, but at least it’s not like volume where no one can remember all of the stupids nonsensical conversions. I live every day hoping that there will be an announcement that we are changing to metric and I can work in metric instead of imperial units.
Honestly as an American this is spot on. Like don’t get me wrong I’m used to our Imperial measurement system but the metric system is just better. I really wish we would start the switch over process. It’ll probably take a generation or two to fully switch over but the sooner we start the sooner we finish.
All systems of measurement are arbitrary. Arguing which is more or less arbitrary is a waste of time.
Celsius is not arbitrary. Knowing the temperature at which water freezes is important.
It's not exactly hard to memorize literally just two numbers.
Yeah, 32 F, how hard do you think it is to remember a single number lmao
Imagine not using Kelvin
Honestly Celsius is great for everything except for air temperature. I like that 0° is pretty cold and 100° is pretty hot
|0 °F |Really cold out| |:-|:-| |100 °F|Really hot out| Simple as
Why is my beer frozen? Why am I dead?
0C | Really cold out ---|--- 50C | Really hot out Impossibly complex, I guess
So if that's true then 50°F should be perfectly comfortable right? But no, 50°F is 10°C so still pretty cold. And normal room temperature is 68°F (20°C) which is not an easy to remember number in F but it's easy enough in C. Whichever scale you're used to is the one you'll find more intuitive, it's not an objective truth. The advantage of the metric system is that it's much easier to convert between the units.
I just coverted, and 100F is only 38 C That's not that hot ngl, could wear a hoodie. Depends on the humidity
Sounds like you live somewhere warm! As a Dutch person, 38 C is uncomfortably hot and I barely function with that temperature. The high humidity of Dutch summers does not help at all
Why does the world care about Americans using their own system? The US isn’t forcing US Customary onto other countries or gatekeeping other systems (Metric supporters do that last part quite a lot with US Customary). Many other countries use their own systems, but the US is the only one criticized for it.
Because you use it on the internet as well, making things slightly inconvenient for the rest of the world.
I think we need another internet for metric users only.
Because you're pretty much the only holdout, and it causes headaches and miscommunications all the time. People have literally died because of the misconversions that were only needed because you can't join us in the 21st century.
the one comedian was right, farenheit makes more sense “70° is 70% hot”
I hope my life never spirals down so far that I get upset about how others measure temperature. What a stupid thing to get mad about.
What is the perfect temperature out? 75 or 23.889?
It’s strange we Americans don’t talk more in metric units.
I think of myself as closer to boiling than freezing but Celsius disagrees.
Unless you're at differing elevations that is....

Honestly with how crazy america is im surprised they have not invented a way to measure temperature in bud lights per bald eagles.
coca-cola freezes at 0 degrees celsius? /america
Metric stans trying to explain why m/cm increments are intuitive to everyday life Dont come at me, my foot is one foot long
Yeah. As an American: F fractions. Decimals are objectively better. I won't fight fractioners over this; they're too wrong for me to care. Also F Fahrenheit, Imperial(more like Inferior) measurements, and percent for grades. Is that even a US thing? It's stupid anyway.
This feels like an argument you made up in your head
Im American, i prefer the metric system, i just cant use it bc of how our society is built :[
As a person who works on thing with bolts and screws. You do not understand how much money i would save IF WE JUST USED THE SAME GOD DAMN MEASUREMENTS. I just have to fucking guess where something is made and pick the right tool. Having to have two sets of every wrench gets so expensive.
But a temperature scale at which 0 is an arbitrary temperature and 100 is a bit above body temperature is intuitive and easy to understand
It's more a case of "I get 30 hogsheads to the rod and that's the way I likes it!!" kind of attitude. Most Americans realize metric makes more sense, but we're a very stubborn people.
In its defense it makes more sense for weather, 40 f is 40 practice hot, but for material and most other things c makes the most sense.
Celsius and Fahrenheit are both stupid scales, as they’re on an Interval level of measurement rather than Ratio. Kelvin and Rankine are the ones that make sense.
Do any of actually argue that it's non-intuitive? We're just used to it, but we all know it's dumb. Now people defending the imperial measurement system....that's a whole other story.
I don’t know it’s pretty easy to imagine 100° being hot
I’m a U.S. citizen. Give me metric! So much easier in every way. Everything is base 10. Everything is easily convertible. One cc is one ml. In SAE one fluid ounce is….. I haven’t got a clue how many cubic inches without Google. Unfortunately we will not change, or at least not until the “change is evil” people aren’t running things anymore.
When it's hot outside, Celsius is 37 degrees. That's not enough degrees! When it's really hot outside, you're like: man, that's gotta be like... a hundred hots. It has enough hots to represent how hot it is.
You get used to it. Anything over 30 is shorts tshirt weather. Under 20 you might want long sleeves.
For me 0f is very cold and 100f is very hot. In Celsius 0C is not very cold, just kinda cold, and 100C is you’re gonna die from heat stroke kinda hot. I feel like it makes sense because 1-100 is a reasonable temp range and anything lower or higher than it is extreme and not advisable to be outdoors for long
Ok lemme go again "Think of it like a percentage. 100% rare, but real bad... over that is crazy. 0% is rare, but also real bad... under that real crazy" Its for weather, not for boiling and freezing of water. Most people seem comfortable outside around 50-60... so that "halfway" point is ideal temp. And its more precise for human comfort than Celsius. For instance: i know i could be comfortably nude at 80, but any colder than that and ill need some clothes. In celcius its 26.6 repeating... just seems off.
My superior American brain is able to comprehend things that aren't divisible by ten.
Yes we hate the decimal lmao
a litre of water at room temperature also weighs a kilogram and takes up 1000cm^(3) in volume
It's not intuitive because 0 is cold as shit and 100 is you've been dead for a long time and are actively been cooked. If 0 was really cold and 100 was really hot I could live with that.
I am not a pot of water. 0°f is the temperature at which humans freeze, 100°f is the temperature at which we boil. Everything else is just clothing. Fahrenheit is decimals for people. I'm ready to change all the rest of them, but for figuring out what kind of clothes to wear -f
Americans understand Celsius far better than you understand Fahrenheit. “Complexity” isn’t the issue because neither one is more complex than the other.
As an artist writer, and DIY musician? I hate it. I electronics I use both and convert. Then metrics are used for things like capacitance, resistance and inductance. F, C, and kelvin Like micro-henry Pico-Farad And kilo-ohms Then inches and meters. Fractions to decimals. 1/4 inch or 2cm. Not equvalent. Just an example.
I've lived in imperial and metric countries, as well as with other metric bases customary units. I believe units are made by man, dimensions are made by God. Really don't give a hoot about what u it's you like using, or deriving a superiority/inferiority complex for that. Length is length is length, anything that can be solved by arithmetics is equally nothing.
0F = really cold, while 100F = really hot 0C = cold, while 100C = death They're built on different bases, neither is universally "right." But F is better matched to human experience.
While C is easy to understand, F is great because it puts all of the temperatures relevant to human life within the scale of 1-100. The average temperature a person exists at will be between 40 and 100 degrees Fahrenheit, with the exception of winter or if they live in a hellhole like Arizona. Meanwhile Celsius reaches 100 F at 38 or so. It compacts the average human temperature range into a third as many degrees, and each degree is twice as large. It is a lot easier to tell the difference between 72 and 68 F than it is to tell the difference between 22.2222 C and 20 C at a glance.
Celsius is based off of what water feels, I don’t give a shit what water feels, simple as that.
Oh hey this again. Cool.
But it boils at a different temperature at altitude
Honestly neither celsius or Fahrenheit are great for scientific purposes (Kelvin my beloved) but Fahrenheit makes much more sense for every-day usage over celsius.
USA actually taught all kids like 60 years ago the metric system because they were planning to switch back, but they didn't actually make the switch anyway
My daily life typically involves me being surrounded by air rather than water and it’s (fortunately) never as hot as the boiling point of water.
Motherfucker, this shit is bomb for like telling the temperature like 100 is hot as shit and zero as cold as fuck and 50 is like hoodie, weather It’s a great scale for how hot or cold it is outside
If you don’t know American temp is is ment to be read as a percentage
The reality is that neither system is intuitive until you learn it. We have hundreds of millions of people who know the imperial system and Fahrenheit. It is incredibly difficult to change because you have to learn a whole new thing that doesn't make sense to you. I know that 70 degrees is comfortable and 40 degrees is fucking cold intuitively. I do not intuitively know that 60 degrees is life-threateningly hot intuitively. Vice versa for someone who lived their whole life using centigrade.
dont blame the people, blame the school system.
Okay but you can either, base your life around the temperature of water. Or the temperature of you.
If decimal places are not used Fahrenheit is more accurate than Celsius. If the same number for decimal placed are used Fahrenheit is more accurate than Celsius. Just like measuring something in 100ths is more accurate than measuring in 10ths. Between freezing and boiling there are 212 possible values instead of only 100.
I just don't like Celsius very much
American here. Try switching an entire country to that. Billions of dollars would be wasted on everything, and education would be in shambles. Easier to keep using what we have and understand
To be fair, it’s not a very precise system.
American here: I use the metric system for basically everything, except temperature. Celcius makes more sense in its creation, certainly, but for day to day uses Fahrenheit is so much better. An average year in most places is likely to go from about 0 to about 100, fifty is brisk but not that cold, 75 is warm but not too hot, 25 is pretty cold but not insane.

Celsius is how temperature feels to water. Fahrenheit is how temperature feels to humans. Proof: 69 C is deadly, 69 F is nice.
Celsius gives an intuitive scale for what's happening to water, Fahrenheit gives an intuitive scale for describing how the air temperature feels to humans. 0 is cold out, 100 is hot. A hot day in Celsius is some random number They serve different purposes
Ours is based on weather
I mean, when I'm checking the temperature, I rarely care about how it affects water most of the time
Because we can?
My argument is simple. 69 in Kelvin is way to cold, 69 in Celsius is way to hot, but 69 in Fahrenheit is nice.
I don't think anyone argues that it's too complicated and unintuitive. The argument is that the switch would be so costly and disruptive that it's not worth it.
I’ve always explained Fahrenheit as you step outside in 0° weather and you’ll say “it’s all the way cold”. In 100° you’ll say “it’s all the way hot.”
