20 isn’t cold at all, it’s perfectly warm.
10 is nippy, but you still warm up quick after a few minutes walking, and get sweaty if you’re working on something.
0 is cold enough for a couple layers. Jumper + jacket so you can take one off if you warm up too much.
-10 doesn’t feel that much different to 0.
-20 is time to put on a thicker coat over the jumper.
