I was looking over a 1980 catalog I have from R.C. Hallett World Champion Bicycles, the US distributor for Andre Bertin bicycles. Here's a section that made me smile:

In 1791, the French decided that the basis for for all linear measurement ought to based on one-ten-millionth of the length of an imaginary line that ran from the North pole to the equator. (Though Paris, of course.)

Never mind that their measurement was less accurate than had they thrown horse-shoes at the moon and calculated their trajectory.

Of course, the meter has been redefined a few times since; At the moment, it is defined as being equal to 1,650,763.73 wavelengths of the orange-red line (corresponding to the unperturbed atomic energy level transition between levels 2p10 and 5d5) in the spectrum of the krypton-86 atom in a vacuum.

Now, who could call THAT arbitrary?

I'm just glad that my favorite vintage bike is French! Otherwise I'd have to deal with those "obsolete and/or oddball dimensions and standards."
