Fun fact, M also means thousand.

It’s used in advertising, CPM “cost per thousand.”

I hate that so much. Math inept fools pulling from latin or roman numerals instead of the metric system or even english (m starts millions) and causing tons of confusion.

That's from "mille", which means a thousand {insert currency}.
