Definition:Volt/Base Units

Definition

The SI base units of the volt are:

$\mathrm V := \mathrm {kg} \, \mathrm m^2 \mathrm s^{-3} \mathrm A^{-1}$

where:

$\mathrm {kg}$ denotes kilograms

$\mathrm m$ denotes metres

$\mathrm s$ denotes seconds (of time).

$\mathrm A$ denotes ampere.

This arises from its definition as:

$\mathrm J \, \mathrm C^{-1}$, that is: joules per coulomb

which is also presentable as:

$\mathrm W \, \mathrm A^{-1}$, that is: watts per ampere.
