How to convert kVA to kW

kVA to kW calculation formula

P(kW) = S(kVA) × PF

The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), multiplied by the power factor PF.


kW = kVA x PF
kilowatts = kilovolt-amps x PF

For example:

Power (S) = 2,5kVA
PF = 0,7

Power (P) = 2,5kVA x 0,7 = 1,75kW
