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.
So,
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
