I hate you break it to you, but "customary units" is what they are called, regardless of the (lack of) prevalence of that custom.

Interesting use of the term _customary_! To add to the complexity of this, weren’t the customary units of length and mass were defined in the U.S in the late 1800’s by reference to international metric standards - the Mendenhall order?
Typically they're called "US customary units" outside of the grand old U. S. of A, who refused to adopt any sort of metric system way back in the 19th century because they were "ungodly".
Perhaps "ungodly" explains current refusal, but original reason U.S. does not use metric is pirates stole the metric standards as they were being shipped over from France.
