Amps to VA Calculator – AC Single Phase & Three Phase
Easily convert amps (A) to volt-amps (VA) for AC single phase and AC three phase circuits. Enter the current in amps and voltage to get the apparent power in VA instantly.
Amps to VA Formula
- AC Single Phase: S (VA) = I (A) × V (V)
- AC Three Phase (Line-to-Line): S (VA) = √3 × I (A) × V (V)
Example Calculations
- AC 1-Phase: 10A, 230V → 10 × 230 = 2,300VA
- AC 3-Phase: 20A, 400V → 1.732 × 20 × 400 = 13,856VA
Amps to VA Table (230V)
