Example of VA to Watts Calculations

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

Watts=VA×Power Factor

Assuming a common power factor of 0.8 for these calculations.

Table of VA to Watts Conversions

Below is a table showing the conversion of various VA values to watts, sorted from smallest to largest, assuming a power factor of 0.8.
