Do US universities still use imperial units in teaching? How much of the teaching content at universities in the US is delivered in imperial units instead of SI?

I imagine that industry (e.g. Engineering) is still stuck using imperial units, but research and physics are much better suited to SI units, so I am interested to know how this is dealt with.
When I was an (engineering, US) undergrad, the textbook in one engineering mechanics class included problems using SI units and problems using imperial units. The problem sets for homework and exams came from the book, and could be in either SI or imperial units.

(You can see these examples in a sample chapter).

Every other class I've taken as a physics and engineering student used SI units exclusively.
