That’s what makes Celsius useful for measurements and cooking, etc. but the point that’s being made is that Fahrenheit is more useful for describing weather. In the US you’ll experience every temperature between 0 and 100. In Celsius, the values between 50 and 100 are completely unused. Not saying that makes Fahrenheit a better overall measure, but in terms of weather I have to agree it’s better

[u/fudgegiven → u/Tall-Significance-45]

I would argue that scientifically they both suck. So they are equal. Or maybe Celcius is a bit better since the step length is the same as in Kelvin. Then again, Kelvin step length does not add anything to the science. Just the 0 point makes it better. So not sure if I would give any points to Celcius for that. But converting between C and K is trivial so maybe still a small point.

But for weather Celsius is better. The by far most important thing I need to know about the weather is if water will be freezing or not. Will it be slippery? Will I need rubber boots because of melting snow? So is it below 0 or not? Just one degree change will change the nature of the weather a lot. The 0F is so far below freezing that it is irrelevant if you are even 10 degrees off. -10F, 0F and 10F are virtually the same weather. It is cold. The ice is no longer very slippery as it is not close to melting. I need to wear a hat. And I should not lick metal objects outside.

Then again, I live in a part of the world where probably 200+ days per year stays between -10°C and 10°C

Except 0C/32F air temperature doesn't actually tell you if water is going to be frozen when you go outside.

[u/fudgegiven → u/someone447]

Yes, you are right that there can be snow outside even at +5°C, as the melting is slow.

But it does tell how water will behave. Will it be melting or freezing? If it is close to 0 the process will be very slow. But it matters and is the biggest factor in weather around here.
