Definition:Electric Field Strength/Dimension

Definition
Electric field strength has the dimension $\mathsf {M L T}^{-3} \mathsf I^{-1}$.

This arises from its definition as:
 * force, with dimension $\mathsf {M L T}^{-2}$
 * per unit electric charge, with dimension $\mathsf {I T}$.

Also defined as
For systems which use electric charge instead of electric current as one of the fundamental dimensions:
 * $\mathsf {M L T}^{-2} \mathsf Q^{-1}$
