Definition
The SI unit of electromotive force is the volt $\mathrm V$:
- $1 \ \mathrm V = 1 \ \mathrm J \ \mathrm C^{-1}$
that is, $1$ joule per coulomb.
In the CGS unrationalised electromagnetic system, the base unit of electromotive force is the abvolt $\mathrm {abV}$.
In the CGS unrationalised electrostatic system, the base unit of electromotive force is the statvolt $\mathrm {statV}$.
