Kilowatts to Amps Calculator
Convert kW to amps for DC, single‑phase, or three‑phase AC circuits. Estimate current, breaker size, and apparent power.
Step 1: Electrical Parameters
⚡ Quick formula
DC: I = P / V | AC single‑phase: I = P / (V·PF) | AC three‑phase: I = P / (√3·V·PF)
Step 2: Power Factor & Options
0.95
📐 Power factor notes
PF is only used for AC. For DC it is ignored (set to 1). Typical motor PF: 0.8–0.95. Leave at 0.95 for general use.

Current vs Power Factor (at fixed voltage)
Useful Formulas
DC: I = P / V
AC single‑phase: I = P / (V × PF)
AC three‑phase: I = P / (√3 × V × PF)
I = current (amps), P = power (kW × 1000), V = voltage, PF = power factor.
√3 ≈ 1.732. Breaker size = I × 1.25 (rounded up).
