Frequency — hertz (SI) is turns per second, engines RPM is revolutions per minute. Integral would produce turn with fractions.
Turn, half turn, quarter turn, used in common language. Centiturn (0.01 turn) or milliturns (0.001 turn) could serve degree role. No need to force a change, degrees already replaced with pi in a middle school, though tau reflects turn better.
Time does not follow angle subdivisions (1/24/60/60 vs 1/60/60), second is SI measure, people can't even abolish DST, no change in foreseeable future.
That said we use spoons and cups on a kitchen, floors to describe building height, inches for plumbing and displays.

Hertz measured in turns, not radians. https://en.wikipedia.org/wiki/Radian https://en.wikipedia.org/wiki/Radian https://en.wikipedia.org/wiki/Turn_(angle) https://en.wikipedia.org/wiki/Turn_(angle) https://en.wikipedia.org/wiki/Hertz https://en.wikipedia.org/wiki/Hertz
- dmoy 6y agoIn precision rifle shooting, milliradian is very common. Minute of angle is also still common. Scopes are sold with both. It sort of depends on the discipline. For example service rifle scopes are almost universally in minutes of angle, while in the Precision Rifle Series the overwhelming majority use scopes in mils. Super confusing is when a scope uses mils for the reticle but minutes of angle for the adjustment. That's just terrible, but they exist.
