Uh, it’s the length a photon travels under vacuum during a time interval between two hyperfine ground states of caesium-133 divided by 299792458. Duh.
Mm science :3 I prefer to think of a meter as roughly 3 light nanoseconds
I love the fact that imperial is legally defined in it’s relation to metric btw :3. Like the US uses metric they just have to abstract it for some reason

Yeah, and you can get Americans to crash out over it.
Ask a silly question… 😜
