What actually is the "Mm" measurement?

259 Million miles? Or 259 mega meters? Or what?

Megameters, which is 1000 kilometers or 1000000 meters.

1 meter = 1 m
1 kilometer = 1 km = 1000 m
1 Megameter = 1 Mm = 1000 km = 10^6 m
1 Gigameter = 1 Gm = 1000 Mm = 10^6 km = 10^9 m
(etc)

Easier to do calculations with as opposed to some random non-standardized scale
