Someone posted here once something like

Farienhiet is how humans feel. Celsius is how water feels. Kelvin is how atoms feel.

I kinda like that.

It only makes sense if you grow up with Fahrenheit. Otherwise Fahrenheit isn't how humans feels since most of us have no concept what these number mean.

If I would just go with 0 - cold 100 - hot I would assume 50 - perfect. But 50 is still chilly. 70-80 feels like it should be getting hot but that's the most comfortable temperature.

Honestly it makes more sense with Celsius. -40 is really cold. +40 is really hot

Again. 0 is still freezing. But in the relative scale it's not so bad

No, Celsius doesn't make more sense in regard to how humans feel. It just feels more intuitive to us because we are used to the numbers. But if you try to explain the scala to someone the numbers feel entirely arbitrary with no real reason behind it. Why is 40 the really hot? 40 is such a weird number for humans.

0 being cold, 100 being hot makes sense, anyone can grasp that concept. But the inbetween steps of Fahrenheit make no sense. It isn't intuitive, it only makes sense if you are used to them. A intuitive scala would be:

0 - cold, you need proper winter clothes 25 - chilly, you need a light jacket 50 - room temperature 75 - getting uncomfortably hot 100 - too hot, heatstroke is a real danger

Mate you talk about Celsius being arbitrary but it's literally the other way around. 0 and 100 in f are bothe completely arbitrary. 0 outside has no real significance. In C its when you can start to expect ice and snow, so gives you actual information about the weather. The f scale could justnas well be 7° to 96° and it would make no difference.

You miss the point of the discussion. The discussion is about how Fahrenheit relate to how humans interact with numbers and relate that number to temperature based on how that temperature feels.

I am not saying Celsius is arbirtray, I am saying that 40 being really hot is a weird number for most humans to associate with "hottest weather you are somewhat likely experience". Of course if you grew up with Celsius it feels second nature. But for someone who isn't familiar with either Celsius or Fahrenheit, the 0 - 100 could be way more intutive. Fahrenheit still fails at this because the numbers between 0-100 don't really add up with what's intuitive.

That's why I said the original argument of "Fahrenheit is how humans feel" doesn't work.

hottest weather you are somewhat likely experience"

Butyoure missing my point. In that there's nothing special about 100°f. It's not like 101f is some super rare or impossible temperature or anything . Or is any major different to 99f.

Of course if you grew up with Celsius it feels second nature. But for someone who isn't familiar with either Celsius or Fahrenheit, the 0 - 100 could be way more intutive.

I did actually grow up on f, until I moved to the UK. C is just a better system. I think you're VASTLY overestimating the utility of the scale going to 100 instead of 40 (and really if you want to get technical you can say C goes from -50 to 50 and that's still a 100 point scale) especially as you can argue the 0-100 scale almost infers a percentile, so gives the false impression that 50f is "50% hot" which it very much isnt, its actually pretty chilly.

For Celsius, it's 0 and under for proper winter clothes and the cutoff for snow (though it can snow above that due to temperature variance at higher altitudes and snow can melt below that due to the sun, so it's a bit of a soft cutoff).

0 - 10 is chilly, pants and coat weather, though you might unzip your coat at the higher end.

10 - 20 is pants and jacket weather, though you'll remove your jacket at the higher end.

20 - 30 is shorts and short sleeve weather and IMO the perfect range.

30 - 40 is getting uncomfortably or even deadly hot, depending on the person and humidity level.

I'm not sure any linear scale will quite accurately represent how people feel.

It makes sense if you're used to 70 being a C average like in school

And Rankine is a sin.

I was mocking up a control panel for a makerspace vacuum former as a potential project (didn't end up happening), and I put in controls for Celsius, Kelvin, Farenheit, and Rankine. Then I wanted a unit more ridiculous than Rankine, so I invented the Nihon. Zero Nihon is the freezing point of Nihonium, and 100 is the boiling point. Except it's the theoretical point, because Nihonium has too short of a half life to actually study.
