Middle of the middle west
The base length of metric units is just an arbitrary length just like any other. They came to the length first and then found something that fit. For instance a cm is defined as the length electromagnetic ray travels in a vacuum in 3.33564095 x 10^-11 seconds. Seems pretty arbitrary to me.
One could say then an inch is the distance a ray of electromagnetic radiation travels in 8.4725...x 10^-11 seconds in a vacuum. A centimeter is .3739 of an inch.
What I do know is that with an imperial system I can use my body as a tape measure when I don't have a tape on me and it works pretty well. Can't really do that well with metric.
