Volts (V) to Kilowatts (KW) Conversion Calculator

convert electrical voltage in volts (V) to electric power in kilowatts (kW). You can calculate kilowatts from volts and amps. Volts to KW formula. You can calculate kilowatts from volts and amps, but you can't convert volts to kilowatts since kilowatts and volts units do not measure the same quantity.

Conversion using the Volts to KW Formula

How to Calculate KW from Volts and Amps using DC line current.

The Real Power P in Kilowatts Kw is calculated as the voltage in volts V, times the current in amps A divided by 1000. Plug these values into the formula:

KW = Volts × Amps 1000

For Example, let's convert 12 volts to KW for a DC circuit with 20 amps of current.

Real Power(P) = Voltage(V) × Current(I) 1000

or, P(KW) = 12 Volts × 20 Amps 1000

or, Real Power = 0.24000 Kw

How to Calculate KW from volts, amps and Power factor pf using AC Single Phase current.

The Real Power P in Kilowatts kw is calculated as the Power factor in pf times the current I in amps A, times the voltage v in volts v divided by 1000. Plug these values into the formula:

KW = pf × Amps × Volts 1000

For Example, let's convert 220 volts to Kw for an AC electrical circuit with 25 amps of current and a power factor of 0.8.

Real Power(P) = Power factor(pf) × Current(I) × Voltage(V) 1000

or, P(KW) = 0.8 pf × 25 Amps × 220 Volts 1000

or, Real Power = 4.400 KW

How to Calculate KW from Volts, Amps and Power factor pf using AC 3-phase current for Line-to-Line Voltage.

The Real Power p in kilowatts Kw is calculated as the square root of 3 times the Power factor in pf times current I in amps A, times the Line-to-Line RMS V_L-L in volts v divided by 1000. Plug these values into the formula:

KW = 3 × pf × Amps × Volts 1000

For Example, let's convert 440 Volts to KW for an AC Electrical circuit with 15 amps of current and a power factor of 0.8.

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(V) 1000

or, P(KW) = 3 × 0.8 pf × 15 Amps × 440 Volts 1000

or, Real Power = 9.14523 KW

How to Calculate KW from Volts, Amps and Power factor pf using AC 3-phase current for Line-to-Neutral Voltage.

The Real Power p in Kilowatts kw is calculated as the 3 times the power factor in pf times the current I in amps A, times the Line-to-Neutral RMS voltage V_L-N in volts V divided by 1000. Plug these values into the formula:

KW = 3 × pf × Amps × Volts 1000

For Example, let's convert 440 Volts to KW for an AC Electrical circuit with 16 amps of current and a power factor of 0.9.

Real Power(P) = 3 × Power factor(pf) × Current(I) × Voltage(V) 1000

or, P(KW) = 3 × 0.9 pf × 16 Amps × 440 Volts 1000

or, Real Power = 16.89600 KW
