How to convert Watt-hours to Kilowatts

How to convert energy in watt-hours (Wh) to electric power in kilowatts (kW).

It is possible to calculate kilowatts from watt-hour and hours, but you cannot convert watt-hours to kilowatt units, since watt-hours and kilowatts represent different quantities.


Watt-hours to Kilowatts calculation formula

The power P in kilowatts (kW) is equal to the energy E in watt-hours (Wh) divided by the time period t in hours (h):

P(kW) = E(Wh) / (1000 * t(h))

So

Kilowatts = Watt-hours / (1000 * hours)

or

kW = Wh / (1000 * h)

Example

Find the power consumption in kilowats when the energy consumption is 15000 watt-hours given a time duration of 3 hours.

P = 15000 Wh / (1000 * 3h) = 5kW
