Definition:Electric Displacement Field/Units

Definition
The SI units of electric displacement field are coulombs per square metre: $\mathrm C \, \mathrm m^{-2}$

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

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