I know it is pedantic, but could someone please enlighten me as to where does MM means millions?

It's so easy to stick to international units, folks. Please. PLEASE!

M is 1,000 in Roman numerals. MM is short for M*M, so 1,000 * 1,000 = 1,000,000 or MM.

The M lives on in languages like Spanish where the word mil means one thousand.
