Is it unreasonably pedantic to want the title here to be "20MM" since the original post was "20 Million" and the "thousand thousand" abbreviation should be correctly used?
- Novosell 3y agoThe symbol to denote a million is M according to the SI.
- opello 3y agoIf this were attached to a noun like "units" (e.g. Munits, like Mb in Megabits) I'd think the SI was a reasonable place from which to draw guidance. But it's attached to the number which to my eye seems like the accounting/finance Roman Numeral style would be expected. Thinking about it more maybe the MM should only mean million when there's a dollar sign. I'm not so confident anymore.
- Sohcahtoa82 3y ago20M is correct and I don't know why people think "million" should be abbreviated as "MM". M is Mega, as in a Million. "thousand thousand" would be "kk".
- opello 3y agoIt's because in finance/accounting the MM is taken from Roman Numerals. I'm not sure why it's got magically implicit multiplication instead of the standard Roman Numeral reading (2000 for MM) but such is life.
