Gaussian units are the same as cgs emu for magnetostatics.
Mx = maxwell, G = gauss, Oe = oersted ; Wb = weber, V = volt, s = second, T = tesla, m = meter, A = ampere, J = joule, kg = kilogram, H = henry
Conversion of magnetic units
| Symbol | Property | Gaussian → SI | |
| Φ | magnetic flux | 1 Mx → 10−8 Wb = 10−8 V⋅s | |
| B | magnetic flux density | 1 G → 10−4 T = 10−4 Wb/m2 | |
| magnetic induction | |||
| H | magnetic field | 1 Oe → 103/(4π) A/m | |
| m | magnetic moment | 1 erg/G = 1 emu → 10−3 A⋅m2 = 10−3 J/T | |
| M | magnetization | 1 erg/(G⋅cm3) = 1 emu/cm3 → 103 A/m | |
| 4πM | magnetization | 1 G → 103/(4π) A/m | |
| σ | mass magnetization | 1 erg/(G⋅g) = 1 emu/g → 1 A⋅m2/kg | |
| specific magnetization | |||
| j | magnetic dipole moment | 1 erg/G = 1 emu → 4π ⋅ 10−10 Wb⋅m | |
| J | magnetic polarization | 1 erg/(G⋅cm3) = 1 emu/cm3 → 4π ⋅ 10−4 T | |
| χ, κ | susceptibility | 1 → 4π | |
| χρ | mass susceptibility | 1 cm3/g → 4π ⋅ 10−3 m3/kg | |
| μ | permeability | 1 → 4π ⋅ 10−7 H/m = 4π ⋅ 10−7 Wb/(A⋅m) | |
| μr | relative permeability | μ → μr | |
| w, W | energy density | 1 erg/cm3 → 10−1 J/m3 | |
| N, D | demagnetizing factor | 1 → 1/(4π) | |
