<P> The watt ( symbol : W ) is a unit of power . In the International System of Units ( SI ) it is defined as a derived unit of 1 joule per second , and is used to quantify the rate of energy transfer . In dimensional analysis it is described by M L 2 T − 3 ( \ displaystyle ( \ mathsf ( ML ) ) ^ ( 2 ) ( \ mathsf ( T ) ) ^ ( - 3 ) ) . </P>
