Amps to Kilowatts calculator

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)

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

* 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 VL-L measured in volts (V)  which is finally divided by 1000.

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

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