kW to Amps calculator

Enter the power in kilowatts (kW), voltage in volts (V), select power factor (PF) from 0 to 1 with a 0.1 step (for AC), then press the Calculate button to get the result in amps (A).

DC kW to amps calculation

Power in kW
Voltage in volts (V)

I(A) = 1000 × P(kW) / V(V)

The current I in amps (A) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by the voltage V in volts (V).

AC single phase kilowatts kW to amps calculation

Power in kW
Voltage in volts (V)
Power factor (PF)

I(A) = 1000 × P(kW) / (PF × V(V))

The phase current I in amps (A) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by the power factor PF, multiplied by the RMS voltage V in volts (V).

AC three phase kW to amps calculation

Line to line voltage

Power in kW
Voltage in volts (V)
Power factor (PF)

I(A) = 1000 × P(kW) / (√3 × PF × VL-L(V))

The phase current I in amps (A) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by square root of 3, multiplied by the power factor PF, multiplied by the line to line RMS voltage VL-L in volts (V).

Line to neutral voltage

Power in kW
Voltage in volts (V)
Power factor (PF)

I(A) = 1000 × P(kW) / (3 × PF × VL-N(V))

The phase current I in amps (A) is equal to 1000, multiplied by the power P in kilowatts (kW), divided by 3, multiplied by the power factor PF, multiplied by the line to neutral RMS voltage VL-N in volts (V).
