How to Convert kilowatts (kW) to kilowatts-hour (kWh)

How to convert power in kilowatts (kW) to energy in kilowatt-hour (kW·h).

Kilowatts to kilowatt-hour calculation formula

The energy E in kilowatt-hour is equal to the power P in kilowatts, times the time period t in hours:

E_(kW·h) = P_(kW) × t_(h)

So

kilowatt-hour = kilowatt × hour

Or

kW·h = kW × h

Example

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

E = 5kW × 3h = 15 kW·h
