WebI was trying out Dimensional Analysis on a few equations and realized that angles have no dimension. Otherwise equations such as s = r θ are not dimensionally consistent. Further, why don't trigonometric ratios have any dimension? PS: I couldn't find any appropriate tag for this question. Could someone re tag as appropriate? Thanks. physics WebPlane angle has radian as units. but these do not come under SI or derived units. Units other than SI units or derived units are called supplementary units.
