# Electric Potential, Potential Difference, and Electromotive Force

aV

## Other Names

emu-of-electric-potential, abV

## Metric (SI) Equivalent

This equivalent and the others below are exact.

## Other Metric (SI) Equivalents with More Basic Units

1×10-8 meter2 kilograms / ampere second3

## Metric (SI) Dimensions

length2 × mass × time-3 × electric-current-1

These are the dimensions of the "electric potential" quantity in SI units. There are other unit systems used in electromagnetics that may assign different dimensions.
