# 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)}

So

kilowatt = kilowatt-hour / hour

or

kW = kWh / h

#### Example

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
