How to convert kilowatts-hour to kilowatts

How to convert energy in kilowatt-hour (kWh) to electric power in kilowatts (kW).

You can calculate kilowatt from kilowatt-hour and hours, but you can't convert kilowatt-hour to kilowatt, since kilowatt-hour and kilowatt units represent different quantities.

Kilowatts-hour to kilowatts calculation formula

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

P(kW) = E(kWh) / t(hr)


kilowatt = kilowatt-hour / hour


kW = kWh / h


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

P = 15 kWh / 3 h = 5 kW
