How to Convert kVA to kW

Kilovolt-amps (kVA) and kilowatts (kW) are both measures of power, but they differ slightly. kVA is a measure of the apparent power while kW is a measure of the real power. These often are different because of equipment power factor.

Power factor is the ratio between apparent power and real power and is a way to represent the amount of power in equipment that’s used but does no real work.

To convert from kVA to kW the power factor needs to be accounted for. This formula can be used for the kVA to kW conversion.

kW = kVA × Power Factor

The real power in kilowatts is equal to the apparent power in kVA times the equipment power factor. To convert, simply add kVA and power factor to the formula above.

For example, let’s find the real power of a piece of equipment with 50 kVA of apparent power and a power factor of 80%.

kW = 50 kVA × .8
kW = 40 kW
