VA to Watts Conversion Calculator & Motor Power Chart

VA to watts Conversion Calculator:

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

Power factor times of apparent power is equal to real power. Let us consider power factor is cos pi, apparent power S in VA and real power P in Watt, by using the above relation,

P(W) =  S(VA) × cos pi

Real power = apparent power * power factor.

Unit wise

Watt = VA * pf

Example:

A turbo alternator is operating at 5000 VA at unity power factor. Calculate the real power in Watt supply through the alternator.

Apply our formula,

P(W) = 5000 * 1

Real power = 5000 Watts

Hence at unity power factor, the real power is equal to the apparent power.

VA to Watt conversion chart:

In below table, you can find out the standard VA rating of the motor and their real power at different power factor. While increasing the power factor, we can increase the real power (rating) of the equipment.
