You can do the same thing with celsius if you live in a country with a different temperature "calendar".

I'm used to the idea that 0C is what splits the year between cold season and warm season. Obviously people from California will see it differently, for example.

So where I live it is like this:

30 or more - hot

15..30 warm

0..15 chilly

-15..0 calendar winter

-30..-15 real winter

..-30 - freezing, kinds younger than 12 don't go to school

Sure, but we usually don't judge things on a scale from -30 to +30.

Judging anything on a scale from 0-10 (or 0-100) is very common.

		Yes, but that the whole problem: this scale kind of suggests that you don't go below 0. But this is not the case here, right? Some people are used to higher temperatures and never seen snow while some people can't even imagine what it's like to have 40C (104F) outside. 0C is a great "common denominator" (irony). We all understand that generally this is when water changes its state and most people know how it feels. And then your imagination can easily go lower or higher. >Judging anything on a scale from 0-10 (or 0-100) is very common. Now consider that many people live in places where 0F is warmer than what you actually have for a good part of a year.
