Watts to VA Conversion Calculator & Convert W to VA

Watts to VA Conversion calculator:

Enter watts: W
Enter power factor:  
   
Result in volt-amps: VA

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

W to VA Conversion Table:

Below mentioned W to VA chart is prepared for the standard motor rating. Hence 750 Watts motor VA rating will be 798 VA at 0.95 pf.
