VA to watt conversion calculator calculates the real power in watts. VA is apparent power. The relationship between the real power(watts) and apparent power(VA) is given below.
When we multiply apparent power(VA) with the power factor, we get the real power in watts. The volt-ampere(VA) is the product of voltage and current.

Examples of VA to Watt Conversion:
A generator is delivering 5kVA to a load at 0.8(lag) power factor. Calculate the real power.
Given data-
Apparent Power = 5kVA
= 5000 VA
Power Factor = 0.8
VA to watt conversion
Real Power(Watts)
P= Apparent Power X Power Factor
P = 5000 X 0.8
P= 4000 Watts
What will be the real power if the power factor is unity?
Real Power(Watts)
P= Apparent Power X Power Factor
P = 5000 X 1
P= 5000 Watts
Therefore, for the unity power factor, the real power and apparent power factor are equal. This is true for a purely resistive load because the power factor of the resistive load is equal to unity.
