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

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

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

I_{(A)} = 1000 × P_{(kW)} / (√3 × PF × V_{L-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 **V**_{L-L} in volts (V).

### Line to neutral voltage

I_{(A)} = 1000 × P_{(kW)} / (3 × PF × V_{L-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 **V**_{L-N} in volts (V).
