The SI unit for million is M, so that should be 3 M (with a space). 3 m would mean 3 minutes.

M is the SI prefix for million (not a unit).

m is the SI unit symbol for meter. Minute is not a SI unit, as the SI unit of time is the second.

Woah, I feel dumb (I knew all this, but my tired brain did a silly while I commented). Thanks for correcting me! I can’t edit my message.

It could also mean 3 meters. Context is everything. The lowercase m would be more widely understood in this context.
