# 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
