Amps to kVA Calculator – AC Single Phase & Three Phase
Easily convert amps (A) to kilovolt-amps (kVA) for AC single phase and AC three phase circuits. Enter the current in amps and voltage to get the apparent power in kVA instantly.
Amps to kVA Formula
- AC Single Phase: S (kVA) = I (A) × V (V) ÷ 1000
- AC Three Phase (Line-to-Line): S (kVA) = √3 × I (A) × V (V) ÷ 1000
Example Calculations
- AC 1-Phase: 10A, 230V → 10 × 230 ÷ 1000 = 2.3kVA
- AC 3-Phase: 20A, 400V → 1.732 × 20 × 400 ÷ 1000 = 13.856kVA
