Anyone come up with a good measure of distance that makes the speed of light a nice round number? I like the metric system, but the meter feels pretty arbitrary. We could do better!
Since 2019, the meter has been defined as the length of the path traveled by light in vacuum during a time interval of 1/299792458 of a second, where the second is defined by a hyper-fine transition frequency of caesium.

Not arbitrary.

I mean, that is pretty arbitrary. The reason the divisor is that specific constant is because we already had meters before we knew the speed of light.
