How to convert watts to VA
How to convert real power in watts (W) to apparent power in volt-amps (VA).
Watts to VA calculation formula
The apparent power S in volt-amps (VA) is equal to the real power P in watts (W), divided by the power factor PF:
S(VA) = P(W) / PF
So volt-amps are equal to watts divided by the power factor.
volt-amps = watts / PF
or
VA = W / PF
Example
What is the apparent power in volt-amps when the real power is 3000W and the power factor is 0.8?
Solution:
S = 3000W / 0.8 = 3750VA
