5.1 Mm?
510 mym
Five point one millimeter of what?
M ≠ m in metric. Example: 1 MB = 1000 kB
M ≠ m in metric
Maybe not in academic notation, but in every day writing, it ABSOLUTELY is used as it and Mm isn't used for kilometer anywhere lol
Also, since we're nitpicking, 5190 rounds to 5200, not 5100 😛
Mm is absolutely used as a shorter form of 1000km where I 'm from, especially when you're talking about the distance you (or your vehicle) travels per year.
