VA to Watts 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 watts (W).

VA to watts calculation

W: 0

P(W) = S(VA) × PF

The real power P in watts (W) is equal to the apparent power S in volt-amps (VA), multiplied by the power factor PF.
