Example of Amps to VA Calculations
To convert amperes (A) to volt-amperes (VA), you need to know the voltage (V) and the power factor (PF) of the load. The formula to convert amps to VA is:
VA=Amps×Volts×Power Factor
Assuming a common voltage of 240V and a power factor of 0.8 for these calculations.
Table of Amps to VA Conversions
Below is a table showing the conversion of various ampere values to VA, sorted from smallest to largest, assuming a voltage of 240V and a power factor of 0.8.
