<P> The watt ( symbol : W ) is a derived unit of power in the International System of Units ( SI ) defined as 1 joule per second and can be used to quantify the rate of energy transfer . Power has dimensions of M L 2 T − 3 ( \ displaystyle ( \ mathsf ( ML ) ) ^ ( 2 ) ( \ mathsf ( T ) ) ^ ( - 3 ) ) . </P>
