How to Convert Kilowatts to Kilowatt-Hours
Kilowatts, or kW, are a measure of electrical power. Kilowatt-hours, abbreviated as kWh or kW·h, are a measure of energy used. One kilowatt-hour is equal to one kilowatt of power consumed over a one-hour time period.
kW to kWh Conversion Formula
kWh = kW × Hours
The energy in kilowatt-hours is equal to the power consumed in kilowatts times the time in hours.
For example, let’s convert 25 kW power used over a 4-hour time period to energy in kWh.
kWh = 25 kW × 4 hours
kWh = 100 kWh
