(My physics prof.) announced the first day of class that in his classroom all problems and discussion would refer solely to metric units, and that there would be no inches, feet, miles, etc in any of the problems or during any of the discussion.
That's what I did for several decades when I was still actively teaching college level physics.
I took it a step further (to add emphasis although it didn't actually DO anything). I announced that, since the Physics text contained some end of chapter problems in non-metric units, that if I should ever accidentally assign one of those, the class was automatically excused from doing the problem.
