European here! For me it's...
Celcius:
0 = Water freezes
100 = Water boils
Fahrenheit as far as I can tell:
~100 = Hot enough that it shows up on the news
~400-450 = Cooking, because our stove is in Fahrenheit for some unknown reason.
All other temperatures in F = no idea.
Why do I care about water boiling when we're talking about weather?
People contain water
Ugly bags of mostly water
