I don’t know about you but I do not only use temperature in order to know … if outside is cold or not

Yeah what maniac would care about something like that

I usually use temperature scales in order to know if my computer is hot, my car/bike engine, my food

Oh, I see, the things that everyone uses temperature for all the time. Perfect sense.

I like to know if my food is freezed or is boling

You all are doing a terrible job of selling me on Celsius here.
