In the CGS system, there are several different sets of electromagnetism units, of which the main ones are ESU, Gaussian, and EMU. Among these, there are two alternative (non-equivalent) units of magnetic dipole moment: 1 statA ⋅ ⋅ cm 2 = 3.33564095 × × 10 − − 14 A ⋅ ⋅ m 2 (ESU) 1 erg G = 10 − − 3 A ⋅ ⋅ m 2 (Gaussian and EMU),
