I have a very basic questions about units for angular momentum. The measure is in kg m^2/s Angular velocity is in radians/s and therefore radians do not appear in the units. Here is my question, can we leave this in degees/s? Sure its not used but is it wrong? If we are dealing with something like tangential velocity for example, angular velocity has to be in radians/s because a linear measure like tangential velocity cannot have degrees as part of the units. It would be wrong to do so. However, in the case of angular momentum, we are measuring an angular quantity. Having degrees in the units should be acceptable. Yes, that never happens but is there a scientific reason that would make it wrong to have degrees in angular momentum? Thanks in advance!
