How come people say 5,000 km and not 5 Mm?
why not just say millions of meters or Mega meters?

    I’ve seen megameters used in the context of astronomical distances, but not terrestrial ones. I think terrestrially, the familiarity of kilometers helps with a sense of scale.

      The beauty of the metric system is you don’t lose a sense of scale from using a higher unit because you can intuitively know 1Mm is 1000km.
