# Amps to VA calculator

Amps (A) to volt-amps (VA) calculator and how to calculate.

Enter phase number, the current in amps, the voltage in
volts and press the *Calculate* button,

to get the apparent power in volt-amps:

## Single phase amps to VA calculation formula

The apparent power S in volt-amps is equal to current I in amps, times the voltage V in volts:

*S*_{(VA)} = * I*_{(A)}* *×* V*_{(V)}

## 3 phase amps to VA calculation formula

The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps, times the line to line voltage V_{L-L} in volts:

*S*_{(VA)} = *√*3
× * I*_{(A)}* *×* V*_{L-L(V)} = 3
× * I*_{(A)}* *×* V*_{L-N(V)}
