Let me explain. Anything below 0F is really cold for a human, and anything above 100F is really hot. The Fahrenheit scale was built around human biology.
0C isn't even that cold, and 100C is literally instant death. Thus, Celsius is less applicable to the human experience and more applicable to the physical properties of water. The typical range of human scale temperatures is like -10 to 40 degrees on the Celsius scale? Makes no sense.
Kelvin is the most scientifically objective scale, but also the least intuitive for humans, because absolute zero is completely outside our frame of reference.
So it's easily demonstrable that Fahrenheit is how people feel, Celsius is how water feels, and Kelvin is how molecules feel.
Be forewarned that I am willing to die on this hill, and any challenges to my position will result in increasingly large walls of text until you have conceded the point 😤
main arguments from below
Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference
Each Celsius degree is nearly two Fahrenheit degrees > Celsius is less granular
The reason I argue the more granular Fahrenheit is more intuitive is because a one degree change should intuitively be quite minor. But since you only have like 40 or 50 degrees to describe the entire gamut of human experiences with Celsius, it blends together a bit too much. I know that people will say to use decimals, but its the same flaw as negative numbers. It’s simply unintuitive and cumbersome.
B) 66F is room temperature. Halfway between freezing (32F) and 100F.
All scales have to be learned, obviously. It’s far easier to create intuitive anchorpoints in a 0-100 system than a -18 to 38 system. Thus, Fahrenheit is more intuitive for the average person.
I should note that if you are a scientist, the argument completely changes. If you are doing experiments and making calcualtions across a much wider range of temperatures, Celsius and Kelvin are much more intuitive. But we are talking about the average human experience, and for that situation, I maintain Fahrenheit supremacy
Final edit: Well, I got what I asked for. I think I ended up making some pretty irrefutable points with these two last ones though. Once again, math saves the day. If somebody wants to continue the discussion make another thread and tag me because this is a bit much for science memes.
further arguments
It’s not about the specific numbers, but the range that they cover. It’s about the relation of the scale to our lived experience. Hypothetically, if you wanted to design a temperature scale around our species, you would assign the range of 0-100 to the range that would be the most frequently utilized, because those are the shortest numbers. It’s not an absolute range, but the middle of a bell curve which covers 95% of practical scenarios that people encounter. It doesn’t make any sense to start that range at some arbitrary value like 1000 or -18.When the temperature starts to go above the human body temperature, most humans cannot survive in those environments. Thus, they would have little reason to describe such a temperature. Celsius wastes many double digit numbers between 40-100 that are rarely used. Instead, it forces you to use more negative numbers.
This winter, many days were in the 10s and 20s where I live. Using Celsius would have been marginally more inconvenient in those scenarios, which happen every winter. This is yet another benefit of Fahrenheit, it has a set of base 10 divisions that can be easily communicated, allowing for a convenient level of uncertainty when describing a temperature.
the end is nigh
Sure, water is a really good system and it works well.
And for F that range is -40 to 104. See how you get 64 extra degrees of precision and nearly all of them are double digit numbers? No downside.
Furthermore F can use its base 10 system to describe useful ranges of temperature such as the 20s, 60s, etc. So you have 144 degrees instead of just 80, and you also have the option to utilize a more broad 16 degree scale that’s also built in.
You might say that Celsius technically also has an 8 degree scale(10s, 30s), but I would argue that the range of 10 degrees Celsius is too broad to be useful in the same way. In order to scale such that 0C is water freezing and 100C boiling, it was necessary for the units to become larger and thus the 10C shorthand is much less descriptive than the 10F shorthand, at least for most human purposes.
Nope, it was built around the highest and lowest extremes some dude could create in his room. Not based on human biology in the slightest. Don't repeat this false information.
Yeah, but counter argument, who gives a shit? The "meme" doesn't say anything remotely close to "from 0 to 100". I don't know why you are under the impression that these scales become inaccurate if you leave the 0-100 range. I live in a region that frequents -40C to +40C over a year- that's centered on zero, so it's already better for "how humans feel" than being centered on 32 and pretending there is some cosmic/celestial/god ordained reason for it.
Still no one giving a shit- the "meme" doesn't remotely even suggest anything related to this.
I don't know why you sign this off with "I'm an obnoxious twat", but I'm perfectly happy with using the block function if the threat is real.
A) Fahrenheit has an appropriate level of granularity for humans
B) Fahrenheit has an intuitive frame of reference for humans
Celsius and Kelvin do not.
I don't want to fight about this I just think it's actually true, and I also think Europeans get insanely defensive about stuff like this for no reason.
A) So is Celsius, you do everything in double digits until you turn on your oven.
B) If 50F was actually room temperature (the middle of too hot and too cold), I could agree. The fact that is is not means for me the intuition is learned and not natural. And that I have to learn a few anchorpoints to convert my own intuition when I ever visit the US.
Idk how your A relates to mine, if anything that's more about the frame of reference, not the granularity. It's good that you rarely have to use triple digits, but you do have to use negative numbers quite frequently.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference
Each Celsius degree is nearly two Fahrenheit degrees > Celsius is less granular
The reason I argue the more granular Fahrenheit is more intuitive is because a one degree change should intuitively be quite minor.

Your point about intuition is moot, imo, because if you didn’t grow up with F it’s just as unintuitive as C is to you.
When you’re used to it the usage of decimals and negative numbers is neither complicated nor unintuitive because you’ve learned to know this intuitively for your whole life.
I could argue, that freezing temps outside being below 0 are unintuitive because it’s obvious to me that negative temps mean it’s literally freezing cold. That’s intuitive for me because I‘ be used that my entire life. Same as room temperature being 20°C. It just makes sense to me because I‘ve always know it that way.
Your "intuitive anchor points" 32 or 66 or whatever are completely nonsensical and unintuitive to someone whose brain is wired in Celsius. Because we don’t think in -18 to 38 but rather -20 to 40, if you want to think of it like that (or -40 to 20 I suppose, if you live somewhere where it’s colder). But in all honesty, in my day to day life, I don’t think about that, because I just know what a celsius value means intuitively.
Fahrenheit is more intuitive for the average American, not the average person.
I don't think you're taking into account that the average person is really bad at math. There's a lot of people around the world that are illiterate.
Anything can be intuitive if you're intelligent enough. But when something is described as intuitive, that implies that it can be easily understood. Put it this way, if F is 1/10 difficulty, C is 2/10 and Kelvin is 5/10.
Would you also argue that Kelvin is intuitive?
Just because Celsius works perfectly fine doesn't mean that Fahrenheit doesn't make more intuitive sense.
I'm sorry, but if you go out on a cold day and see a barrel of water with ice on the top, you immediately know it's freezing cold and we're in the negatives. Water freezing being 0 is a solid, objective anchor point.
"When it feels cold" will vary from someone that lives in a generally warm climate to someone that lives in a colder climate but water will freeze at 0. That means the warm and cold people can base their range around that and intuitively understand how far or above or below 0 the extreme hot or cold areas are. Generally -40 to 40 are the extremes of livable areas.
Sure, water is a really good system and it works well.
And for F that range is -40 to 104. See how you get 64 extra degrees of precision and nearly all of them are double digit numbers? No downside.
Furthermore F can use its base 10 system to describe useful ranges of temperature such as the 20s, 60s, etc. So you have 144 degrees instead of just 80, and you also have the option to utilize a more broad 16 degree scale that's also built in.
You might say that Celsius technically also has an 8 degree scale(10s, 30s), but I would argue that the range of 10 degrees Celsius is too broad to be useful in the same way. In order to scale such that 0C is water freezing and 100C boiling, it was necessary for the units to become larger and thus the 10C shorthand is much less descriptive than the 10F shorthand, at least for most human purposes.
Fahrenheit stays winning in my book.
It could easily be argued that weather having to deal in so high numbers is a con for F and the positive negative distinction of C is an easy to understand system of how far from snow are we. As others I don’t believe one is particularly better than the other for the purpose of describing day to day weather. Your arguments ring hollow to me and often seem based on heuristics for F and often with the “close to this value” caveat making it seem like a stretch.
That might be true but only if you live in a climate that actually has temperatures from about 0-100F. If you don’t (which most people don’t), it’s just as arbitrary. If you live somewhere it’s freezing regularly, it’s good to know if the roads will be icy (below 0°C) or not (above 0°C). If you live somewhere where it’s regularly above 100F and rarely below 50F, that scale doesn’t really work intuitively either, anymore.
And of course Kelvin isn’t intuitive but that’s because it isn’t centered around anything within the human experience. Frozen and boiling water are within the human experience however. And again, if you’d have only ever used K, it’d come just as easy to you as F does now.
