How to Convert Volts to Kilowatts

Volts (V) to kilowatts (kW) conversion requires current (I) via P=V⋅I/1000, as volts measure electric potential and kilowatts measure power. Learn more about kilowatts

DC Volts to Kilowatts Calculation

P = V × I / 1000

P = Power (kilowatts)

V = Voltage (Volts)

I = Current (Amperes)

Note: Multiply Volts by Amps and divide by 1000

AC Single Phase Volts to Kilowatts

P = PF × V × I / 1000

P = Power (kilowatts)

PF = Power Factor

V = Voltage (Volts)

I = Current (Amperes)

Include Power Factor for AC calculations

AC Three Phase Volts to Kilowatts

Line to Line Voltage Calculation

P = √3 × PF × V × I / 1000

P = Power (kilowatts)

PF = Power Factor

V = Line voltage (Volts)

I = Line current (Amperes)

Line to Neutral Voltage Calculation

P = 3 × PF × V × I / 1000

P = Power (kilowatts)

PF = Power Factor

V = Phase voltage (Volts)

I = Phase current (Amperes)

Key Terms

Power Factor (PF)

The ratio between real and apparent power in AC circuits, ranging from 0 to 1.

Line Voltage

The voltage measured between any two lines in a three-phase system.

Phase Voltage

The voltage measured between a line and neutral in a three-phase system.
