The imperial system America uses is better optimized for quantities people expect to use in real life frequently without requiring awkward decimals or larger numbers etc. better ergonomics.
With imperial you have weird fractions instead of decimals. To know that 3/4“ is larger than 1/2“ I have to actively think, decimals come pretty naturally (which was probably different in times before people went to school and learned to do math on paper)
To know that 0.32 m is smaller than 43 cm I have to actively think, but I'm guessing you don't. I've never had to think about 3/4 vs 1/2. Even 5/16ths vs 1/4 is intuitive for me.
When we use fractions for measurements, the denominator is virtually always a power of two. The only one I can think of that isn't is a fifth of alcohol, which is really just its own unit at this point.
Neither 1/36th or 1/12th are used, and the other two aren't fractions. We don't say six and a twelfth feet, we say six feet one inch. With distance, fractions are only used for fractions of an inch (apart from trivial uses like "one and a half miles").
I feel like neither system is inherently better outside of familiarity and I don't care which is used I'm just tired of having to own two sets of tools.
