Bohr magneton

Unit of magnetic moment, for electron, defined by μ B = eh / 4πm e C, where e is the charge, h is Planck's constant, c is the velocity of light, and m e is the rest mass, so that μ B = 9.27x10 - 24 JT -1 . The nuclear Bohr magneton is defined by 
 eh μB μN = ———— = ———— = 5.05 x 10-27JT-1 4πMc 1836
M being the rest mass of the proton.
