I have a question about dimensional analysis in the formula of the gyration frequency of synchrotron radiation of a relativistic particle (electron of charge e and mass m) in a magnetic field B. Leaving aside the adimensional Lorentz factor γ and numerical factors, the formula reads v ~ (e * B) / (m * c) (see for example eq. 9 in https://www.astro.utu.fi/~cflynn/astroII/l4.html). The dimensions of frequency are already given in the expression (e * B) / m, so how does the speed of light c in the denominator fit in here? I am afraid this must be something obvious about units system or convention, but I am confused. Help would be appreciated.
