Web13 May 2024 · P = W / t P = F * s / t The unit of power in the metric system is the watt, which is equal to one joule per second. In the English system the unit of power is the horsepower hp which is equal to 550 foot-pounds per second. WebAdditionally, this unit is often seen elsewhere when the energy usage of power consuming devices, structures, or jurisdictions is under consideration. We can parse out the conversion from kilowatt-hours to joules in this way: 1 W = 1 J/s and a kilowatt is 1000 W while one hour is 3,600 seconds, so 1 kWh is (1000 J/s) (3600 s)=3,600,000 joules.
