How to convert kWh to watts

How to convert energy in kilowatt-hour (kWh) to electric power in watts (W).

You can calculate watts from kilowatt-hour and hours. You can't convert kilowatt-hour to watt unit since kilowatt-hour and watt units represent different quantities.

Kilowatts-hour to watts calculation formula

The power P in watts (W) is equal to 1000 times the energy E in kilowatt-hour (kWh), divided by the time period t in hours (hr):

P(W) = 1000 × E(kWh) / t(hr)


watt = kilowatt-hour / hour


W = 1000 × kWh / h


What is the power consumption in watts when the energy consumption is 15 kilowatt-hour for time duration of 3 hours?

P = 1000 × 15 kWh / 3 h = 5000 W
