How to convert electric power in kilowatts (kW) to electrical voltage in volts (V)?

kW to volts conversion  formula in DC

V=The voltage V in volts
P=the power P in kilowatts
I=the current I in amps

V(in volt) = 1000 × P(in kW) / I(in amps)

So that using above formula we can say that volts(V) are equal to 1000 times kilowatts(KW) divided by amps(A).

volt(V) = 1000 × kilowatts(KW) / amp(A)

or you can re-write this as

V = 1000 × kW / A

Let’s take example
Example#1
I want to calculate the voltage in volts where  the power utilization is 5 kilowatts(kW)
and the current flow in the wire is 4 amps
V = 5 kW / 4A = 1.25V

How to convert AC single phase watts to volts

V=The RMS voltage V in volts
P= the power P in watts
PF=power factor PF
I=the phase current I in amps

V(V) = 1000 x P(in kW) / (PF × I(A) )

So that you can say that volts(v) are equal to watts(kW) divided by pf times amps

volts(v) = 1000 × kilowatts(kw) / (PF × amps)

or you can re-write this formula as

V = 1000 × W / (PF × A)

Let’s take one Example
Example#2
Calculate the RMS voltage in volts where the power utilization is 5 kilowatts,and the pf is 0.8 and the current is 4 amps
V = 1000 × 5kW / (0.8 × 4A) = 1562.5V

kilo-watts to volts calculation formula in AC three phase system.

VL-L=The line to line RMS voltage VL-L in volts
P=the power P in kilowatts
PF=the power factor PF times
I=the phase current I in amps:

VL-L(V) = 1000 × P(in kW) / (√3 × PF × I(A) )

So that you can say that volts(v) are equal to kilowatts(kW) divided by √3 times pf times amps.

volts = 1000 × kilowatts / (√3 × PF × amps)

or rewrite this formula as

V = 1000 × kW / (√3 × PF × A)

Let’s take one Example
Example#3
find out the RMS voltage in volts where the power utilization is 5 kilowatts, the pf is 0.8 and the phase current flow in the circuit is 3.123 amps?
V = 1000 × 5kW / (√3 × 0.8 × 3.123A) = 1155.44002V
