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.
A lot of it is individual adaptation. People in colder climates may wear clothing very similar to people in warmer climates, but are just used to the colder temperatures. Someone from a colder country would probably end up getting heat stroke in your country while wearing the same clothing as you.
Whoah there, 20c° is shorts weather, let’s not get carried away. In winter, it’s a comfy setting for the thermostat (speaking from New England). If it were 32c°, I’m sitting inside in air conditioning
30c is the perfect temperature. It's not hot it's nice. 40c is fine if you drink water and use shade. It's like saying 5c is dangerous bc it can kill you if you don't wear a jacket.
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.
