How to convert kW to kWh

kW to kWh calculation formula

E(kWh) = P(kW) × t(h)

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


kWh = kW x h
kilowatt-hour = kilowatt x hour

For example:

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

Energy (E) = 10kW x 2h = 20kWh
