Bohr magneton calculation

It is known that Bohr magneton is defined as (e.h_bar)/(2.m.c) where e is electron charge, h_bar is Planck's constant, m is electron rest mass. I'm just not sure about c. Is it the speed of light in vacuum? When calculating it, c is assumed to be 1, the same as in general relativity. Can anyone help?

    c is the speed of light in a vacuum but you only use it if you are calculating the Bohr magneton in CGS units. In SI units, there should be no c.

    Does the definition say that there should be no c in SI?

    Sorry, that should be gaussian cgs units but yes
