How to Convert Volts to Kilowatts
Volts (V) to kilowatts (kW) conversion requires current (I) via P=Vโ I/1000, as volts measure electric potential and kilowatts measure power. Learn more about kilowatts
DC Volts to Kilowatts Calculation
P = V ร 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 ร V ร 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 = โ3 ร PF ร V ร I / 1000
P = Power (kilowatts)
PF = Power Factor
V = Line voltage (Volts)
I = Line current (Amperes)
Line to Neutral Voltage Calculation
P = 3 ร PF ร V ร 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.
