kW to kWh Calculator
Convert kilowatts to kilowatt-hours — turn a device's power draw in kW into the energy it uses over time. The key is that kW is power and kWh is energy: kWh = kW × hours. Enter the power and how long it runs to get the kWh (the unit your utility bills).
Energy = power × time: kWh = kW × hours. To go the other way, kW = kWh ÷ hours. kW is power (the rate); kWh is energy (what your utility bills).
