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

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

The power *P* in kilowatts (kW) is equal to the energy *E* in
watt-hour (Wh), divided by
1000 times the time period *t* in hours (h):

*P*_{(kW)} = *E*_{(Wh)}* */* *
(1000 × *t*_{(h)})

So

kilowatts = watt-hour / (1000 × hours)

or

kW = Wh / (1000 × h)

What is the power consumption in kilowatts when the energy consumption is 15000 watt-hour for time duration of 3 hours?

*P* = 15000 Wh / (1000 × 3 h) = 5 kW
