Enter the current in amps (A), 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 kilowatts (kW).

## DC Amps to kW calculation

P_{(kW)} =I_{(A)} × V_{(V)} / 1000

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

## AC single phase Amps to kW calculation

P_{(kW)} = PF × I_{(A)} × V_{(V)} / 1000

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

## AC three phase Amps to kW calculation

### Line to line voltage

P_{(kW)} = √3 × PF × I_{(A)} × V_{L-L (V)} / 1000

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

### Line to neutral voltage

P_{(kW)} = 3 × PF × I_{(A)} × V_{L-N (V)} / 1000

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