Watts to kWh Calculator
To use watts to kWh calculator, simply enter the watts and the number of hours they were used for and click ‘Calculate‘. The calculator will display the corresponding kilowatt-hours used. You can reset the input fields at any time by clicking ‘Reset‘.
Watts to kWh Calculation
The energy E in kilowatt-hours (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000:
E(kWh) = P(W) × t(hr) / 1000
For example: let’s find the kWh of 3000 watts for 2 hours.
E(kWh) = 3000 × 2 / 1000 = 6 kWh
