Fuck no. It does NOT make sense. If the metrics people were pragmatists, it would be:
It would be:
decagallons, hectogallons, kilogallons, etc!!!!
They could have adopted ANY STANDARD BASE UNIT THEY WANTED.
They chose to pick some arbitrary BULL SHIT. "Oh, let's make the meter...let's make it based on...the wavelength of Hydrogen, or some shit...!"
Well, fine. Fuck them, then. All base units are arbitrary. If they were serious about getting people to adopt that nonsense, they would have picked an arbitrary base unit that was relatable to people, not some nonsense bullshit that was relatable to what...atoms?
Their system rots, and it will continue to rot. Yeah, the American educational system is fine! YEAH, THEY TAUGHT ME ABOUT THE METRIC SYSTEM!!!
In history class.
