Volts (V) to kilowatts (kW) calculator.

Enter the voltage in volts, current in amps and press the *Calculate* button to get the power in watts:

## 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 *V*_{L-L} in volts (V) divided by 1000:

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

≈ 1.732 × * PF *×* I*_{(A)}* *×* V*_{L-L(V)} / 1000
