How to convert Volts to kilowatts?

volts to kilowatts calculation formula in case of Direct Current

P=The power P in kilowatts (kw)
V=the voltage V in volts (V)
I=the current I in amps (A)

P(kW) = V(in Volts) × I(in Amps) / 1000

So that you can define kw are equal to the voltage(V) times Current(I) in amps divided by 1000

kilowatts = volts(V) × amps(A) / 1000

or you can re-write this formula like that

kW = V × A / 1000

Let’s take an example
Example#1
Find out the power(P) in kilowatts where the current is 5A and the voltage(V)is 10V in the circuit.
P = 10V × 5A / 1000 = 0.05 kW

volts to kilowatts calculation formula in AC single phase

P=The real power P in kilowatts (kW)
PF=the power factor PF
I=the phase current I in amps (A)
V=the Root Mean Square voltage V in volts (V)

P(kW) = Power Factor × I(in Amps) × V(in Volts) / 1000

So that you can define kilowatts(kwh) are equal to PF times cuurent(I) in amps times volts(V)

kilowatt = PF × amps(A) × volt(V) / 1000

or

kW = PF × A × V / 1000

Let’s take an example
Example#2
Calculate the power(P) in kw where the PF is 0.8 and the current(I) is 5A and the Root Mean Square voltage(V) in the circuit is 100V
Apply the formula for soltution
P = 0.8 × 5A × 100V / 1000 = 0.4 kW

volts to kilowatts calculation formula in case AC three phase

P=The real power P in kilowatts (kW)
PF=the power factor
I=the phase current I in amps (A),
VL-L=the  line to line Root Mean Square voltage VL-L in volts (V)

P(kW) = 1.732 × Power Factor × I(in Amps) × VL-L(in Volts) / 1000

So that you can define “kw are equal to 1.732 times  PF times the Current(I) in amps times volts(V) divided by 1000

kilowatt = 1.732 × PF × amps(A) × volt(V) / 1000

or you can re-write this formula like that

kW = √3 × PF × A × V / 1000

Let’s take an example
Example#3
Find out the power(in kilowatts) where the PF is 0.8 and the current(I) is 5A and the voltage(V) in the circuit is 100V
The power P is equal to power factor of  0.8 times current of 3 amps times the voltage of 110 volts divided by 1000.
P(kW) = 1.732 × 0.8 × 5A × 100V / 1000 = 0.6928kW

How many volts are in a kilowatt?

1W=1J/1s (power=energy per second)
1W=1A.1V (electric power=current.potential differential)
1KW=1000W (K=Kilo=1000)
A kilowatt is a unit used to measure the rate of energy transfer. A volt is a unit used to measure the potential energy of a charge.So it’s like you asked how many miles per hour are in a gallon of gas.
But there are many formulas to define relationship between voltage to power, .
The easiest is:

P=V*I

Which says that the Power P (in Watts, if you like) equals the Voltage V times the rate of charge flow I (in Amperes).
