>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.
If you came to my workplace and used a single 'M' everyone would have the same response here but inverted - how using a single M makes no sense and is inaccurate.
I work in advertising where "CPM" is a common metric (cost per milli). So using a single M still means thousand, will MM means million.
