>Have committed to $22MM of protein I've never understood this convention and it always causes my brain to short-circuit when trying to read it. Is that $22 Million Monies, or $22 MegaMillions I'm assuming that the shorthand is supposed to be read as: $22 Million So then I spend the next 5 minutes stuck in a feedback loop of what the hell am I supposed to be thinking.
So MM is thousand thousand's, or million.
The reason it was adopted in finance was because M means thousand, except in English where we adopted M to mean million.
Of course metric units where M = million makes more sense today, though. It's a legacy thing that stuck around.
