(1) one is not supposed to use any but the "1000 times"
versions of units, hence mm, m, km are OK,
hectares and Angstroms e.g. are not.
"cm" is a classic example of
something that it is suggested one no longer use,
but that is widely used --- often in wonderfully
inconsistent ways right next to mm and m.

(2) Where did I say Celsius?
