To calculate Amps to VA, select phase (single or three phase) first, insert value of amps and line to line volts then press Calculate Button to get the result of volt-amps (VA). Swap to VA to Amps calculator.

## How to Calculate Amps (A) to volt-amps (VA)

Single phase amps to VA Formula

S (VA) = I (A) × V (V)

Power S in volt-amps equal to current I in amps, multiply the voltage V in volts.

Three phase amps to VA Formula

**Line to line voltage**

S (VA) = √3 × I (A) × VL-L (V) = 3 × I (A) × VL-N (V)

Power S in volt-amps equal to square root if 3 current I in amps, times the line to line voltage VL-L in volts.
