Using units of angle wasn't practical because angles are in reality unitless, and adding units makes them inconsistent with a simple numeric input.
Any thoughts?

Sorry to enter this thread a little late, but...
I START with this conceptual notion; angle is the measure of rotation. I think of rotation as ill-defined fundamental unit (#8 of 7), such as temperature, time, etc. related to but separate from length. Thoughts?

SlideRule
It is also measure of time ie. in EE with phasors (f=constant) if we get philosophical P=U*I*Cos(Phi), as it is there for the difference of the phase of the I and U in timedomain. Now when phasors are mentioned, will there be traditional non-tagged method of using angles, by just using bare numbers. I think these two methods can't be separated in discussion they must work together and I go as far as saying that tagging should be more like an option to those who are jumping between O/(decided slicing method).

Ie. If I'm creating impedance (or any Dance) from capacitor 1/(j*2*Pi*f) etc. edit(.. and adding it ..) to existing impedance in polar representation in degrees I wouldn't want it to be some symbolic mess because of the 2*Pi which is radian representation of on full O.

Interesting subject, I like to read these on MoHPC. Would be nice to know what angle is in an eyes of mathematician percentage, direction, factor, way of divide Italian food ??
