# Amps to kW calculator

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

Current in amps (A)
Voltage in volts (V)

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

Current in amps (A)
Voltage in volts (V)
Power factor (PF)

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

Current in amps (A)
Voltage in volts (V)
Power factor (PF)

P(kW) = √3 × PF × I(A) × VL-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 VL-L in volts (V), divided by 1000.

### Line to neutral voltage

Current in amps (A)
Voltage in volts (V)
Power factor (PF)

P(kW) = 3 × PF × I(A) × VL-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 VL-N in volts (V), divided by 1000.
