Joule is used to measure what
NettetSI Unit of Power. Watt is the SI unit of power (W). One watt is equivalent to one joule of energy transferred in a second. 1 Watt=1 J/s=kgm2/s2. Since the metric system is divided into base units and derived units, we get (kgm2/s2) when we convert joules to base units. This is the formula for converting watts into base units.
