Watts to kWh Calculator
Easily convert watts (W) to kilowatt-hours (kWh). Enter the power in watts and the time in hours to get the energy in kWh instantly.
Watts to kWh Formula
- kWh = (Watts × Hours) ÷ 1000
Example Calculations
- 1000 W for 2 hours → (1000 × 2) ÷ 1000 = 2 kWh
- 500 W for 3 hours → (500 × 3) ÷ 1000 = 1.5 kWh
