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

    Aside of kilometers there used to be “myriameter” (a myriad meters = 10,000 m = 10 km).

    Fun thing, in Sweden they use mil for 10 km. In Finland there’s peninkulma for 10 km, but it’s very archaic.
