# Volts to kilowatts calculator

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)}* *Ã—* 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 *Ã—* I*_{(A)}* *Ã—* 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)} = *âˆš*3
Ã— * PF *Ã—* I*_{(A)}* *Ã—* V*_{L-L(V)}
/ 1000

â‰ˆ 1.732
Ã— * PF *Ã—* I*_{(A)}* *Ã—* V*_{L-L(V)} / 1000
