### kW to volts conversion formula in DC

V=The voltage V in voltsP=the power P in kilowatts

I=the current I in amps

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

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

**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 voltsP= 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) )**

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

**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 voltsP=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) )**

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

**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
