Regarding Michael's comments:[...]
I don't totally disagree with Denker and others who want to say that
"radians" are units, but dimensionless units, but it sure causes problems
for students who are trying to do dimensional analysis.
Not if they are careful.
Also, converting units is a *different* activity than doing dimensional
analysis. Dimensional analysis mostly involves power counting of a set
of base dimensions. When doing dimensional analysis *none* of the
dimensionless quantities contribute to the dimension of the result of a
product or quotient of mutliple qunatities *no matter* which units any
dimensionless quantity is measured in. But when converting units (or
