Enter the current in amps (A), voltage in volts (V), then press the **Calculate** button to get the result in volt-amps (VA).

## Single phase Amps to VA calculation

S_{(VA)} = I_{(A)} × V_{(V)}

The apparent power **S** in volt-amps (VA) is equal to the phase current **I** in amps (A), multiplied by the RMS voltage **V** in volts (V).

## 3 phase Amps to VA calculation

### Line to line voltage

S_{(VA)} = √3 × I_{(A)} × V_{L-L(V)}

The apparent power **S** in volt-amps (VA) is equal to square root of 3, multiplied by the phase current **I** in amps (A), multiplied by the line to line RMS voltage **V**_{L-L} in volts (V).

### Line to neutral voltage

S_{(VA)} = 3 × I_{(A)} × V_{L-N(V) }

The apparent power **S** in volt-amps (VA) is equal to 3, multiplied by the phase current **I** in amps (A), multiplied by the line to neutral RMS voltage **V**_{L-N} in volts (V).
