Here's an easy way for disadvantaged yanks to learn Celsius:

40C = 104F perfect hot tub temp
30C = 86F hot day
20C = 68F nice cool day
10C = 50F chilly day
0C = 32F freezing

Commit these to memory, then it's exactly 9F for every 5C in between. (or about 2:1)

[da fak with the downvotes? Just refuse to learn?]

    You give multiple references and say remember these and then do some estimations. Just subtract 30, divide by 2. 80F is approximately 25C. I'm not cooking meth here I'm arguing on the Internet.

    Fine but I'm offering a simplified and exact conversion method that mostly only requires memorizing four numbers
