You shock me. Of course, I am saying that, Are you saying that it wasn't the intention of Napoleon's savants to divide the polar circumference of Earth into 40,000 equal parts (kms)? Do you take the fact that they didn't fully succeed as proof that it cannot be done?
Of course, you can divide the same circumference into 21,600 equal parts with no fractional remainder, as well.
BTW, check out the following site:

I seem to recall that Stecchini says that nautical miles were obtained from the equatorial circumference at some time in prehistory. A nautical mile is also the same as geographical minute. Thus, 360 degrees times 60 minutes equals 21,600 minutes (nautical miles) It was meant as the distance the sun travels along the Earth equator in four seconds (21,600 x 4 = 86,400 seconds = 24 hours)
This would mean that if you lost your watch in prehistorical times, but you did not lose your n. mile measuring rod you could have regained your time by noting how long it took the sun to cover the distance of a given number of n. miles. I hope you understand this concept..
Equatorial circumference - 40, 076.5 km / 21,600 = 1851.8553935185185
So, one nautical mile should be 1851.855.. meters
One stadium should then be 185 meters 18 centimeters and 5.5 millimeters long.
