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 volts to kW calculation

P_{(kW)} = I_{(A)} x 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 volts to kW calculation

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

The 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 volts to kW calculation

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

The 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**_{VL-L} in volts (V), divided by 1000.
