MM refers to a thousand thousand, as M is the Roman numeral for 1000. MM was the standard way of indicating a million, as far as I knew, until the last decade or so. I think most people just use a single M now. I sometimes still use MM though. |
I've never seen MM over here in Europe. mm has always had a fixed meaning, millimeters or 1/100th of a meter.
