Amps to kilowatts calculator

Amps (A) to kilowatts (kW) calculator.

Select current type, enter current in amps, voltage in volts, power factor for AC circuit and press the Calculate button (DC = Direct Current, AC = Alternating Current):

Select current type:  
Enter current in amps: A
Enter voltage in volts: V
   
Power result in kilowatts: kW

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

DC amps to kilowatts calculation

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

P(kW) = I(A) × V(V) / 1000

AC single phase amps to kilowatts calculation

The power P in kilowatts (kW) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V) 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 in kilowatts (kW) is equal to square root of 3 times the power factor FP times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V) divided by 1000:

P(kW) = 3 × PF × I(A) × VL-L (V) / 1000

Calculation with line to neutral voltage

The power P in kilowatts (kW) is equal to 3 times the power factor FP times the phase current I in amps (A), times the line to neutral RMS voltage VL-N in volts (V) divided by 1000:

P(kW) = 3 × PF × I(A) × VL-N (V) / 1000
