I have a Canadian penpal/internet friend who explained how Celsius works. Since 0 is freezing temperature it means that when it’s reaching 0 degrees it’s time for snow! Below 0 it’s time for ice skating! She dislikes using Fahrenheit because she prefers knowing what the temperature means for the environment. So Fahrenheit is for people. Celcius is for water and good for cooking & the weather. I still prefer Fahrenheit being raised on it. But I can respect Celcius.
