How to convert real power in kilowatts (kW) to apparent power in kilovolt-amps (kVA).

kW to kVA calculation formula

The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the Power Factor PF:

S(kVA) =  P(kW) PF

So kilovolt-amps are equal to kilowatts divided by the power factor.

kilovolt-amps = kilowatts / PF


kVA = kW / PF


What is the apparent power in kilovolt-amps when the real power is 3 kW and the power factor is 0.8?


S = 3kW / 0.8 = 3.75kVA
