A meter is defined by taking the fixed numerical value of the speed of light in vacuum c to be 299,792,458 when expressed in the unit m/s, where the second is defined in terms of the cesium frequency ΔνCs (the unperturbed ground-state hyperfine transition frequency of the cesium 133 atom).
And now you know how far a meter is.
A foot is the length of some king’s foot.

Amazing. I’ve learned more about mathmatics today than in 4 years of H.S. 😫
You only went to high school for 4 years? LOSER! I went for six.
Using Trigonometry..
I’m pretty sure there’s a way to calculate that into dog years.
Don’t know much trigonometry…that was year 7
Don’t know too much trigonometry? Don’ know much biology,
But I do know some of ya have too much time on hand,
Maybe we should start our own band…
(Sorry..my Canadian Cactus weed kicked in..never mind…)
Sounds like the 30% stuff but it really sounds like my Rattlesnake Tequila.
Duh. Everyone knows that. I didn’t know that thing about the king’s foot though
However, in a pinch, the number of feet I have for estimation purposes = 2. And, given the same circumstance, the amount of cesium I have = 0. America wins.
I Love how cesium reacts violently with water and air though. My middle school science teacher put on a demonstration improperly and it blew his toupee right off. No one knew he was wearing one…or even cared.
… and that’s how we learned toupee attention.
Yes ..or take 3 licks with the long board. Yikes. Not that teacher but another one gave me licks once for loaning a dude a pencil during testing.
The girls could get by with murder..and nothing. I should have became an Activest against it.
A foot is 12 inches. An inch is defined by science and official weights and measures as exactly 26.2 millimeters. So we’ve been using the metric system all this time and almost nobody knew.
