NASA's DART spacecraft changed an asteroid's orbit...
Okay but they didn't give it in meters per second, they gave it in micrometers per second. Converting to micrometers per second is exactly as much arithmetic as converting to meters per day.

No, it is not. It is in fact no arithmetic at all, if you understand how SI works.

no, what? µ is the dimensionless number 10^-6, just like k is the dimensionless number 10^3.

And you are doing what with that dimensionless number? Multiplying?

Yes, it's one multiplication in both cases.
Multiplying/dividing by 1 million is way easier than by 86400 though.

I would argue that multiplying 10 by 86400 is just as easy as multiplying 10 by any other number. Hint, it's the same as multiplying a number by 10.
