How to convert kW to Wh

kW to Wh calculation formula

E(Wh) = 1000 x P(kW) × t(h)

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


Wh = 1000 x kW x h
watt-hour = 1000 x kilowatt x hour

For example:

Power (P) = 10kW
Time period = 2 hours

Energy (E) = 1000 x 10kW x 2h = 20000Wh
