Definition:Electric Polarization/Units

Definition
The SI unit of electric polarization is the coulomb per square metre: $\mathrm {C / m^2}$.

In the CGS unrationalised electromagnetic system, the unit of electric polarization is the electromagnetic unit of electric displacement $\mathrm {e.m.u.}$

In the CGS unrationalised electrostatic system, the unit of electric polarization is the electrostatic unit of electric displacement $\mathrm {e.s.u.}$
