In my view, because pi crops up unavoidably in math, if you concoct a "unit" to get rid of pi in one place, it will simply crop up somewhere else, perhaps in a denominator.
For instance: The ratio of rise to run for small angles.
Working in optics, radians are such nice units: A milliradian is a millimeter per meter or a "mil" per inch.
