How to convert kW to Wh

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

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

 

Kilowatts to watt-hour calculation formula

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

E(Wh) = 1000 × P(kW) × t(h)

So

watt-hour = 1000 × kilowatt × hour

or

Wh = 1000 × kW × h

Example

What is the energy consumption in watt-hours when the power consumption is 5 kilowatts for time duration of 3 hours?

E = 1000 × 5kW × 3h = 15000 Wh
