Amps to VA Caluclator

Amperes to Volt Ampere Conversion Calculator

Select phase #:  
Enter amps: A
Enter line to line volts: V
Result in volt-amps: VA
It is a conversion calculator which is used to convert the current in Amps (A) and the voltage in volts (V) to Volt-amps (VA). It is simple and requires the units to be filled in the appropriate cells to perform an accurate conversion. The Calculate and Reset button will be of much help while using the calculator as they execute different functions according to their use.

The first step you need to do is to select the phase. It can either be a single phase or a three phase. The next text fields will require you to enter the current in amps and then the line to line voltage respectively. Once the cells are filled completely, you can click on the Calculate button which executes the conversion.

For example, if you have 50 currents in amps and a line to line voltage of 100 Volts, then your results in Volt-amps will be 5000 (VA). The same procedure can be followed when you want to calculate the Volt-amps using different units. It is always important to use the rest button when you want to perform new calculations as it erases everything in a single click.

In case you are calculating using a three phase, you will follow the same arrangement by entering the amps and line to line volts in their appropriate cells. If you have 50 amps and 100 volts in a three phase, then you will have a result in volts of 8660.2540378 VA.

There are certain formulas which the calculator utilizes in performing the conversions;

Calculation of a Single Phase amps to VA
S (VA) = I (A) x V (V), which means that the apparent power in volt-amps is calculated by multiplication of the current in amps times the voltage in volts.

Calculation of a three phase amps to VA
S (VA) = √3 x I (A) x V L-L (V) = 3 x I (A) x V L-N (V), which means that the apparent power in Kilovolts-amps, is calculated by multiplying the square root of three by the current in amps. Then multiplying by the line to line voltage in Volts.

The Amps to VA calculator has been useful in performing the conversions within the shortest time and gives accurate information depending on the entered values. It is always important to start by selecting the phase to avoid wrong calculated results. The reset button restores everything to the original arrangement. Hence you will have to be sure in the chosen period.
