Example of Watts to VA Calculations

To convert watts (W) to volt-amperes (VA), you need to know the power factor (PF) of the load. The formula to convert watts to VA is:

VA=Watts/Power Factor

Assuming a common power factor of 0.8 for these calculations.

To convert 100 watts to VA at a power factor of 0.8:

VA=100/0.8=125 VA

Convert 1000 Watts to VA

To convert 1000 watts to VA at a power factor of 0.8:

VA=1000/0.8=1250 VA

Convert 1500 Watts to VA

To convert 1500 watts to VA at a power factor of 0.8:

VA=1500/0.8=1875 VA

What Is a VA?

A volt-ampere (VA) is a unit of apparent power in an electrical circuit. It represents the product of the root mean square (RMS) voltage and RMS current. Unlike watts, which measure real power, VA measures apparent power, which includes both real power and reactive power. Apparent power is the combination of both real power (which does actual work) and reactive power (which only sustains the electric and magnetic fields in the circuit).
