Somewhat off-topic: why "2k kilometers" instead of 2 megameters? I do realize that in daily life people rarely use distances of that order of magnitude, but the semantic connections between kilobits<>megabits, kilowatts<>megawatts appears to be entirely accessible to essentially all adults, so why use the awkward "thousands of kilometers" instead?

I'm admittedly American, but I've literally never heard "megameters" used outside of a classroom. I know what 1000km is like without thinking, but I have no immediate intuition for a megameter is unless I think about it.

Just because people are so used to kilometers and for many people the conversion is too difficult. You overestimate the intelligence and education of average adults and I am dead serious about this, I did studied this a bit.

We would only need 4% of the range of mega to express any earthly distance. I guess that's why we don't bother.

Be the change.
