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
or
kVA = kW / PF
Example
What is the apparent power in kilovolt-amps when the real power is 3 kW and the power factor is 0.8?
Solution:
S = 3kW / 0.8 = 3.75kVA
