Definition
Electric field strength has the dimension $\mathsf {M L T^{-3} I^{-1} }$.
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:
- $\mathsf {M L T^{-2} Q^{-1} }$
