Truly and deeply bizarre how the former English colonies have evolved with measurement systems.
As someone who works in construction, I think about these archaic concepts.
To divide into halves, 2 is enough. To divide by both halves and thirds, you have to go to sixths.
That makes little sense, since you often have to divide into halves twice, or quarters.
A system that divides easily by halves, thirds, and quarters, is base 12. Surprise!
If you want to go to the next level with proportions instead of approximations, using 5ths, base 60. Surprise Again!
Nobody gives a damn about 7ths, of course. (4 f_cking twenty?)
So then "THE FRENCH" come along and count their fingers and say "10s make everything easy! Do this!"
And millions of years of evolution go out the window.
IBM buckling springs were made in the USA, and if you don't have Imperial tools, then go jump in the lake.
After the Revolution, we only kept what was important, the English language, Magna Carta, the penny, and Imperial measurements.
