You forgot that whenever the temperature exceeds 37C everyone says "it's 100 degrees out!"

edit: also, every proper cookbook.

Also an American saying "sub-zero" means it's really very cold. Basically the difference between a fridge (approx 0 degC) and a freezer (-18 degC).

		Very specifically, cold enough for salt water to freeze. Useless trivia. If you dump salt into ice water, it reliably goes from 32 F to 0 F. Which makes it cold enough to make ice cream with.
