The Mendenhall Order marked a decision to change the fundamental standards of length and mass of the United States from the customary standards based on those of England to metric standards.
It was issued on April 5, 1893, by Thomas Corwin Mendenhall, superintendent of the United States Coast and Geodetic Survey, with the approval of the United States Secretary of the Treasury, John Griffin Carlisle.
The US public are really just pretending that they don't use metric.
I also like the fact that feet are are composed of inches in base 12. The promise that decimal brings some deep utility doesn't really materialize in most other contexts, and time is still base 60.
In my view, people who use metric pretend they like using metric. I mean, the unit of temperature is often expressed in divisions that are 0.1 apart, both because the basic units range and scale aren't particularly useful for human experience, and because "centidegree" is pretty difficult to actually "conjugate" in the system.
Neither system is particularly great, they're mostly just familiar, and outside of a few peculiar cases aren't very distinguished from each other.
It's not clear how this "redundancy" your aiming for would benefit us.

That was actually the point I was trying to get at. Thank you.
