Magnetic susceptibility can be calculated from magnetisation M and magnetic field strength H, with the SI units:

Quantity	Equation	SI units	CGS units	Conversion factor F such that SI = F·CGS
Volume magnetic susceptibility $M$ - magnetisation (A/m) $H$ - magnetic field strength (A/m)	$$ χ_\text{vol} = \frac{M}{H} $$	(unitless) ≡ (A/m)/(A/m)	(unitless)	$4π$
Mass magnetic susceptibility $ρ$ - mass density (kg/m³)	$$ χ_\text{mass} = \frac{χ_\text{vol}}{ρ} $$	(m³/kg)	(cm³/g)	$4π×10^{-3}$
Molar magnetic susceptibility $ρ$ - mass density (kg/m³) $m_\text{mol}$ - molar mass (kg/mol)	$$ χ_\text{mol} = \frac{χ_\text{vol}·m_\text{mol}}{ρ} $$	(m³/mol)	(cm³/mol)	$4π×10^{-6}$
