kVA to kW Calculator – AC Single Phase & Three Phase
Easily convert kilovolt-amps (kVA) to kilowatts (kW) for AC single phase and AC three phase circuits. Enter the apparent power in kVA and power factor to get the real power in kW instantly.
kVA to kW Formula
- AC Single Phase: P (kW) = S (kVA) × PF
- AC Three Phase (Line-to-Line): P (kW) = S (kVA) × PF
Example Calculations
- AC 1-Phase: 2.3kVA, PF 0.8 → 2.3 × 0.8 = 1.84kW
- AC 3-Phase: 13.856kVA, PF 0.9 → 13.856 × 0.9 = 12.470kW
