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 kW to volts calculation formula

To convert electric power in kilowatts (kW) to electrical voltage in volts (V), you can use the following formula for direct current (DC) systems:

V(V) = 1000 × P(kW) / I(A)

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

volt = 1000 × kilowatts / amp

or

V = 1000 × kW / A

Example

  • V is the voltage in volts,
  • P is the power in kilowatts, and
  • I is the current in amps.

To use the formula, simply substitute the values for P and I into the equation and solve for V.

For example, if you have a power consumption of 5 kilowatts and a current flow of 3 amps, you can calculate the voltage in volts like this:

V = 5 kW / 3A = 1666.666V

This means that the voltage in the circuit is 1666.666 volts.

It's important to note that this formula only applies to direct current (DC) systems. If you are working with an alternating current (AC) system, you'll need to use a different formula to calculate the voltage.

AC single phase watts to volts calculation formula

To convert electric power in kilowatts (kW) to RMS voltage in volts (V) for an alternating current (AC) system, you can use the following formula:

V(V) = 1000 × P(kW) / (PF × I(A) )

So volts are equal to watts divided by power factor times amps.

volts = 1000 × kilowatts / (PF × amps)

or

V = 1000 × W / (PF × A)

Example

  • V is the RMS voltage in volts,
  • P is the power in kilowatts,
  • PF is the power factor,
  • I is the phase current in amps.

To use the formula, simply substitute the values for P, PF, and I into the equation and solve for V.

For example, if you have a power consumption of 5 kilowatts, a power factor of 0.8, and a phase current of 3.75 amps, you can calculate the RMS voltage in volts like this:

V = 1000 × 5kW / (0.8 × 3.75A) = 1666.666V

This means that the RMS voltage in the circuit is 1666.666 volts.

It's important to note that this formula only applies to alternating current (AC) systems. If you are working with a direct current (DC) system, you'll need to use a different formula to calculate the voltage.

AC three phase watts to volts calculation formula

To convert electric power in kilowatts (kW) to line to line RMS voltage in volts (V) for a three phase alternating current (AC) system, you can use the following formula:

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

So volts are equal to 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

  • VL-L is the line to line RMS voltage in volts,
  • P is the power in kilowatts,
  • PF is the power factor, and
  • I is the phase current in amps.

To use the formula, simply substitute the values for P, PF, and I into the equation and solve for VL-L.

For example, if you have a power consumption of 5 kilowatts, a power factor of 0.8, and a phase current of 2.165 amps, you can calculate the line to line RMS voltage in volts like this:

V = 1000 × 5kW / (√3 × 0.8 × 2.165A) = 1666V

This means that the line to line RMS voltage in the circuit is 1666 volts.

It's important to note that this formula only applies to three phase alternating current (AC) systems. If you are working with a different type of AC system or a direct current (DC) system, you'll need to use a different formula to calculate the voltage.
