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).
So,
kWh = kW x h
kilowatt-hour = kilowatt x hour
For example:
Power (P) = 10kW
Time period = 2 hours
Energy (E) = 10kW x 2h = 20kWh
