Metric “dozenalisation” would be perfectly viable, and metric-dozenal units would still look nothing like USA units.
I’ll use length for the example. All of them in base 10, just for clarity. (Also the name of the units would be different, but I’m not changing them for this example.)
- metric-decimal: 10⁻³ km = 10⁻² hm = 10⁻¹ dam = 10⁰m = 10¹dm = 10²cm = 10³mm
- metric-dozenal: 12⁻³ km = 12⁻²hm = 12⁻¹ dam = 12⁰m = 12¹dm = 12²cm = 12³mm
- USA units: 1/1760mi = 1yd = 3ft = 3*12 in = 3*12*6 P = 3*12*6*12 p
Are you noticing what the USA units do? They don’t stick to a base.
What. I had to websearch this because it sounds too silly, but apparently it’s true.
But, really, even if it used saner numbers (like 12:3:24:8:3), it still feels nothing like a “metric dozenal” would look like. It’s missing the two things the metric system did right:
