I didn't downvote you, but MM in Roman numerals is million. It is also common enough to represent roman numerals in lowercase that mm, as used here, is totally valid.

[k_f → dyarosla]

Actually, MM in Roman numerals is 2,000, not a million.

[dyarosla → k_f]

You’re right. Don’t know what I was thinking. Guess it’s an accounting only thing

[imbusy111 → dyarosla]

Million is M, not mm or MM or M&M

[noahmbarr → imbusy111]

I believe some parts of the world, particularly in Europe, interpret $500M as $500 * 10^3 (not $500 * 10^6)...So some use $500MM to universally avoid this confusion

[icedchai → imbusy111]

mm and MM are very common ways express "million" in finance. M, mm, MM all mean the same thing.

[dyarosla → imbusy111]

Thousand is M.

[imbusy111 → dyarosla]

In SI, M is million same as k is a thousand.
