## Watts to VA calculation formula

S_{(VA)} = P_{(W)} / PF

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

So,

*VA = W / PF*

*volt-amp = watt / PF*

**For example:**

*Power (P) = 350W*

*PF = 0,7*

*Apparent power (S) = 350W / 0,7 = 500VA*
