Definition:Watt (Unit)/Base Units

Definition
The SI base units of the watt are:


 * $\mathrm W := \mathrm {kg} \, \mathrm m^2 \mathrm s^{-3}$

where:
 * $\mathrm {kg}$ denotes kilograms
 * $\mathrm m$ denotes metres
 * $\mathrm s$ denotes seconds (of time).

This arises from the definition of the watt as $\mathrm {J s}^{-1}$, that is, joules per second.
