No need to convert? What do you mean? Are you saying if I just intrinsically knew Celsius for weather I wouldnāt have to convert Celsius? Because thatās obviously true, but Iām just explaining I donāt intrinsically know Celsius in that way.
Also, even if I did get to know Celsius really well, I would still have to convert it every time someone uses Fahrenheit, which is pretty much all the time in the US.
Lastly, what do you mean, saying 0 C is ādangerously coldā and suggesting that below that temp is outside of the bounds of what is used for weather? Where I live the temperature stays below 0 C for long periods of time, never going above it.
If you know those two numbers, 0 and 40, you can get a general idea of what the temperature is in Celsius without doing any math. If you hear 20, you know thatās a moderate temperature because itās right in between. If you hear 30, you know thatās fairly warm. If you hear 10, you know thatās chilly but not freezing. Below 0 or above 40 are extreme cold and extreme heat, respectively.
