Millions is usually abbreviated to MM for this reason.

  No, MM is an abject abuse of Roman numerals (which means 2,000), as near as I can tell thanks to a nomenclature distortion originally involving CPM (cost per thousand impressions). I can't get over how messed up MM=million is.

    "mm" is frequently used in finance and probably predates the existence of CPM

  So millimeters, then? :) "M" is used quite frequently for million along with "K" for thousand. "MM" as million is used in conjunction with "M" for thousand, but that's a different notation set. "M" & "K" usage is generally much more popular than "MM" and "M", at least in any areas I've been.

    > So millimeters, then? :) The difference between mm and MM is rather easy to spot.
