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 2 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

“What is this commie ‘meter’? Give me measurements in the feet of the dead monarch whom my ancestors rebelled against!” Or something like that :3
