VA to kW calculator

Enter the apparent power in volt-amps (VA), select power factor (PF) from 0 to 1 with a 0.1 step, then press the Calculate button to get the result in kilowatts (kW).

VA to kW calculation

kW: 0

P(kW) = S(VA) × PF / 1000

The real power P in kilowatts (kW) is equal to the apparent power S in volt-amps (VA), multiplied by the power factor PF, divided by 1000.
