How to convert VA to Watts

VA to watts calculation formula

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.

So,

W = VA x PF
watt = volt-amp x PF

For example:

Power (S) = 4500VA
PF = 0,7

Power (P) = 4500VA x 0,7 = 3150W
