You can basically put a "%" after a fahrenheit temperature and read it as "percentage of a really hot day" and you'll get a pretty good idea what it feels like outside.

It's pretty well calibrated as a 0-100 scale for human temperature perception.

I moved from a cold climate to a tropical climate and let me assure you there's no human universal understanding of what's comfortably hot or cold, definitely not to the point of putting a percentage on it. I can walk around in a T-shirt and shorts at 17C (62f) while locals will be wrapping up in scarves and talking about how freezing it is. Meanwhile they'll be fairly comfortable at 35C (95f), at least if the humidity isn't high, and I'll be stuck in with the AC blasting.

So in other words Fahrenheit is a western centric measurement (or at least, temperature climate centric), while Celsius is universal.

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
