French not only got the Meter wrong - They hid their mistakes
The Arrogant French decided to take it upon themselves to make a measure for "all the people of the world" and went about it by appointing Delambre and Mechain to partake in the famed meridian expedition of 1792-1799 to calculate the length of the meter based upon the size of the Earth. The meter was to be one ten-millionth the distance from the pole to the equator.

Problem is, Mechain made a mistake in his calculations, StUpId! Which he then covered up, A$$hoLe!

Now the entire universe uses the screwed-up meter; its off by 0.2mm. Scientists has even further defined the meter more precisely:
"1,650,763.73 wavelengths in vacuum of the radiation corresponding to the transition between levels 2p10 and 5d5 of the krypton 86 atom."

Currently the meter has an estimated relative standard uncertainty of ± 2.5 x 10–11

Even with this mind-bending precision, it is still off by 0.2mm, THANKS FRENCHIES!
