kW to Amps Calculator
Convert kilowatts to amps for DC, single-phase and three-phase circuits.
Inputs
kW
V
Ignored for DC
Results
- Current
- 12.74 A
Formula
DC: I = P ÷ V
Single-phase: I = P ÷ (V × PF)
Three-phase: I = P ÷ (√3 × V × PF)
Assumptions & limits
- P is electrical input power; for motors divide shaft kW by efficiency first.
Worked example
7500 ÷ (1.732 × 400 × 0.85) = 12.74 A.
