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

DC Volts to KW Calculation formula

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:

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

or, P(KW) = V(V) × I(A) 1000

or, KW = Volts × Amps 1000

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

Single Phase Volts to KW Calculation formula

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:

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

or, P(KW) = pf × I(A) × V(V) 1000

or, 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.

3-Phase Volts to KW Calculation formula

Calculation with 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:

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

or, P(KW) = 3 × pf × I(A) × V(V) 1000

or, 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.

Calculation with Line to Neutal 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:

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

or, P(KW) = 3 × pf × I(A) × V(V) 1000

or, 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.

Frequently Asked Questions - FAQs for Volts to KW Calculator

What is the formula for volts to kilowatt (kW)?

An electrical theory tells us that for a single-phase system, kW = (V × I × PF) ÷ 1,000. kW = (V × I) ÷ 1,000.

What is kVA to kW?

For example, a 200kVA generator with a power factor of 0.8 outputs 80kW actual power; 200 kVA × 0.8 = 160 kW.

Is 6 kWh 1 unit?

6 unit of electricity = 6 kWh. The electricity used is generally charged for in unit of electricity'. Killowatt-hours is the product of watts × time (1 kilowatt = 1000 watts).

What is 1 voltage?

1 Volt is defined as energy consumption of 1 joule per electric charge of 1 coulomb. 1V = 1J ÷ C.

Is 1 watt equal to 1 amp?

How Many Watts in 1 Amp? The wattage in 1 amp depends on the voltage of the system. Using the formula for DC conversion: Watts = Amps × Volts, at 120 volts, 2 amps would equal 240 watts.
