How to convert kilowatts to volts

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

You can calculate volts from kilowatts and amps, but you can't convert kilowatts to volts since kilowatts and volts units do not measure the same quantity.

DC kilowatts to volts calculation formula

The voltage V in volts (V) is equal to 1000 times the power P in kilowatts (kW), divided by the current I in amps (A):

V_(V) = 1000 × P_(kW) / I_(A)

So volts are equal to 1000 times kilowatts divided by amps.

volt = 1000 × kilowatt / amp

or

V = 1000 × kW / A

Example

What is the voltage in volts when the power consumption is 0.045 kilowatts and the current flow is 3 amps?

V = 1000 × 0.045kW / 3A = 15V

AC single phase kilowatts to volts calculation formula

The RMS voltage V in volts (V) is equal to 1000 times the real power P in kilowatts (kW), divided by the power factor PF times the current I in amps (A):

V_(V) = 1000 × P_(kW) / (PF × I_(A) )

So volts are equal to 1000 times kilowatts divided by power factor times amps:

volts = 1000 × kilowatts / (PF × amps)

or

V = 1000 × kW / (PF × A)

Example

What is the voltage in volts when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the current is 3.75 amps?

V = 1000 × 0.33kW / (0.8 × 3.75A) = 110V

AC three phase kilowatts to volts calculation formula

The  line to line RMS voltage V_L-L in volts (V) is equal to 1000 times the real power P in kilowatts (kW), divided by square root of 3 times the power factor PF times the current I in amps (A):

V_L-L(V) = 1000 × P_(kW) / (√3 × PF × I_(A) )

         ≈ 1000 × P_(kW) / (1.73 × PF × I_(A) )

So volts are equal to 1000 times kilowatts divided by square root of 3 times power factor times amps.

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

or

V = 1000 × kW / (√3 × PF × A)

Example

What is the voltage in volts when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the current flow is 2.165 amps?

V = 1000 × 0.33kW / (√3 × 0.8 × 2.165A) = 110V
