Cylindric or spherical coordinates : Angles in milimeters !??!

using Comsol 4.1 for the directivity simulation of a speaker, I tried to plot the SPL on a circle surrounding my speaker's model, with the azimuth angle abscissa, using a cylindric or a spherical coordinates system (I tried both).
The suprising problem I have, is that the angle axis is graduated in [mm] instead of degrees or radians. Since the range is [0:3148.xxxxx] mm i can't find any correspondance with angles (nor with radius of the circle, I tried different values)
Does someone have an explanation about this kind of physic's mistake ?
Thanks a lot.
