Whether or not you grow up with it, you have to use an extra decimal point to differentiate between noticeably different indoor temps, and you can't say "it's in the 20s" or something and know what to wear. Memorizing 32˚F for freezing is a one-time thing, which really only matters for ice. You might have snow at 40˚F or no snow at 0˚F. Believe it or not, people don't seem to know the ˚F boiling point of water, probably cause it's just not a factor in everyday life. Your kettle whistles when it's boiling.
