    Huh? Why would you switch to miles from kilometers?

    And IMHO megameters aren’t used that often because there is rarely anything useful to measure with it. Using a different unit makes you lose your sense of scale (e.g. the earth has a radius of ~7000km, not 7Mm) and for astronomy megameters aren’t big enough most of the time (and you might as well use lightseconds/years because gigameters give no real intuition of scale).
