PowerConvert™ Fast Electrical Power Calculators
kVA to kW Calculator
Convert between apparent power (kVA) and real power (kW) using the power factor. Edit either side and the other follows.
Real Power · kW
Apparent Power · kVA
kVA = 1 kW ÷ 0.8
How it is calculated
kW = kVA x power factor. kVA = kW / power factor.
1.25 kVA at power factor 0.8 is 1 kW. 1 kW at 0.8 is 1.25 kVA.
Frequently asked questions
How do you convert kVA to kW?
Multiply the kVA value by the power factor. For example, 1.25 kVA at power factor 0.8 is 1 kW.
How do you convert kW to kVA?
Divide the kW value by the power factor. For example, 1 kW at power factor 0.8 is 1.25 kVA.
What power factor should you use?
Use the load power factor from the equipment nameplate. If unknown, 0.8 is a common assumption for mixed loads.
