Temperatur - sh.itjust.works

It’s easy to convert though. (212-32)/100 = 1.8. So you multiply your temperature in C by 1.8, and then add 32, and you have your temperature in Fahrenheit. So if it’s 30C out, (30*1.8) +32 = 86F.

It is, admittedly, easier to convert centimeters to inches; that conversion is exactly 2.54cm/in.

You don’t need to do a conversion, you can just learn them intuitively. 0 is dangerously cold, 10 is cold, 20 is comfortable, 30 is hot, 40 is dangerously hot.
0 is when snow turns to ice, so slipping becomes a thing to be aware of. But more like -5 to -10 degrees since direct sunlight tends to melt it. It’s not really that cold unless you’re sitting naked outside.
