IMO metric is missing a critical measurement that is roughly the size of "a foot".
Most measurements in one measuring system have very similar equivalents in other measuring systems or useful approximations, like a pound being 1/2 a kilo, a liter being about a quart, or a meter being about a yard. Even various ancient chinese measurements can be similar like this.
Except the metric system seems to have eschewn the common measurement of "About the length of a human foot". It confuses me.
What do you call a footlong submarine sandwich in the metric system? A third-meter-long? A decimeter-long? It wouldn't fit into the power-of-ten based system.
