How to Convert Kilowatts to Kilowatt-Hours

Kilowatts, or kW, are a measure of electrical power. Kilowatt-hours, abbreviated as kWh, 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
