Power in watts (W) to energy in kilowatt-hours (kWh) calculator and calculation formula.

Enter the power in watts, consumption time period in hours and press the *Calculate *button:

So 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

What is the energy consumption in watt-hour when the power consumption is 4000 watts for time duration of 3 hours?

*E* = 4000W × 3h / 1000 = 12 kWh

What is the energy consumption in watt-hour when the power consumption is 6000 watts for time duration of 3 hours?

*E* = 6000W × 3h / 1000 = 18 kWh

What is the energy consumption in watt-hour when the power consumption is 7000 watts for time duration of 3 hours?

*E* = 7000W × 3h / 1000 = 21 kWh

What is the energy consumption in watt-hour when the power consumption is 8000 watts for time duration of 3 hours?

*E* = 8000W × 3h / 1000 = 24 kWh

Here is a conversion Table converting common values of watts to kilowatt hours, over a duration of one hour and one day.
