### Watts to VA Conversion calculator:

Enter Real power in watts and apparent power in VA at the above-mentioned calculator to get the VA. Here the relationship between the real power P and apparent power S is that the real power divided by the power factor is equal to apparent power.

Apparent power (VA) = real power (W) / power factor

*S*_{(VA)} =* P*_{(W)} / *PF*

In simple words,

Volt-Amp is equal to Watt divided by the power factor.

Hence, for converting W to VA,

VA = W / pf

**Example: **

Calculate the VA rating of the 15000 Watts, 0.96pf single phase transformer.

Apply, our formula

VA = 15000 / 0.96

Apparent Power *S*_{(VA)} = 15625 Volt – Amp
