## Amps to Kilowatts calculator

We are offering the Amps (A) to kilowatts (kW) calculator to help you with calculations, check now!

All you need is to select the current type, and enter the voltage in volts, current in amps, and add the value of power factor for the AC circuit and hit the = button (where, DC = Direct Current, AC = Alternating Current)

* Use e for the scientific notation. E.g: 5e3, 1.45e12, 4e-8

## DC amps to kilowatts calculation

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

**P _{(kW)} = I_{(A)} × V_{(V)} / 1000**

## AC single phase amps to kilowatts calculation

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

**P _{(kW)} = PF × I_{(A)} × V_{(V)} / 1000**

## AC three phase amps to kilowatts calculation

#### Calculation with line to line voltage

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

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

#### Calculation with line to the neutral voltage

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

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