Volts to kilowatts calculator

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


It is used to convert the electrical voltage in volts (V) to the electric power in Kilowatts (kW). It is simple to use, and the accuracy depends on the values entered in the cells. Start by selecting the current type before filling in the voltage in volts and current in amps. Click on the ‘Calculate' button to give you the power result in Kilowatts. The ‘Calculate' and ‘Reset' buttons have been programmed to perform their intended functions with a single click.

DC volts to kilowatts calculation formula

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

P(kW) = V(V) × I(A) / 1000

AC single phase volts to kilowatts calculation formula

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

P(kW) = PF × I(A) × V(V) / 1000

AC three phase volts to kilowatts calculation formula

The power P in kilowatts (kW) is equal to square root of 3 times the power factor PF times the 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

            ≈ 1.732 × PF × I(A) × VL-L(V) / 1000
