kW to Amps Calculator – DC, AC Single Phase & Three Phase
Easily convert kilowatts (kW) to amps (A) for DC, AC single phase, and AC three phase circuits. Enter the power in kW, voltage, and (for AC) the power factor to get the current in amps instantly.
kW to Amps Formula
- DC: I (A) = 1000 × P (kW) ÷ V (V)
- AC Single Phase: I (A) = 1000 × P (kW) ÷ (PF × V (V))
- AC Three Phase (Line-to-Line): I (A) = 1000 × P (kW) ÷ (√3 × PF × V (V))
Example Calculations
- DC: 2.3kW, 230V → 1000 × 2.3 ÷ 230 = 10A
- AC 1-Phase: 1.84kW, 230V, PF 0.8 → 1000 × 1.84 ÷ (0.8 × 230) = 10A
- AC 3-Phase: 12.47kW, 400V, PF 0.9 → 1000 × 12.47 ÷ (1.732 × 0.9 × 400) = 20A
