How to Convert kW to Volts?

If you are looking to choose the best power station or a battery backup for your home, it's important to note the electrical units like kilowatts and volts. Kilowatts is the unit of energy that determines the electricity consumption of appliances and gadgets. Volts, on the other hand, represent the energy potential. The kW to volts conversion helps you make informed decisions about the power station you need for your home.

What Is kW to Volts?

A watt is the measurement of power. One watt is defined as the rate at which the work is performed when one amp of current flows through a 1 volt of electrical potential difference. A kilowatt measures how much power an electric appliance consumes. Mathematically, one kilowatt is equal to 1000 watts.

Volts are the electrical potential unit, also called electromotive force. It generally represents the potential difference between two ends of a conducting wire carrying one ampere of current. Voltage is the energy per unit charge driving electric current around a closed DC electrical current.

The volts and kilowatts are two electrical units directly related to each other. One kilowatt is equal to the multiplication of amps, volts, and 1000.

Kilowatts = Amps × Volts × 1000

The higher the watts or kilowatts of the power station, the more electricity it can supply to the appliances. Jackery Explorer Portable Power Stations have high capacities (or high watt values) to charge most home or outdoor gadgets safely.

How to Convert kW to Volts?

There are many formulas to convert kW to volts in DC circuits, AC single phase, and AC three phase.

DC kW to Volts

The voltage in volts is equal to 1000 times the power in kilowatts, divided by the current in amps.

Formula: V (V)  = 1000 × P (kW) / I (A)

Example: If the power consumption is 5 kilowatts and the current flow is 2 ampere, the voltage in volts will be equal to 1000 × 5kW / 2A = 2500V.

AC Single Phase kW to Volts

The voltage in a single-phase AC circuit is equal to 1000 multiplied by the power in watts, divided by the power factor times the current in amps.

Formula: V (V)  = [1000 × P (kW)] / [PF × I (A)]

Example: If the power consumption is 10kW with a phase current of 4A and power factor of 0.8, the voltage in volts is: (1000 × 10) ÷ (0.8 × 4) = 3125V.

AC Three Phase kW to Volts

The line-to-line voltage in volts is equal to 1000 times the power in kilowatts, divided by the square root of 3 times the AC phase current in amps times the power factor times.

Formula:  (V) = 1000 × P (kW) / (√3 × PF × I (A))

Example: If the power consumption is 3kW and the phase current is 1.73A, the RMS voltage in volts will be (1000 × 3kW) / (√3 × 0.8 × 1.73A) = 1255.23V.

On the other hand, if you're calculating the line-to-neutral voltage of the three-phase AC circuit, the formula will be:

Formula:  (V) = 1000 × P (kW) / (3 × PF × I (A))

Example: If the power consumption is 3kW and the phase current is 1.73A, the RMS line-to-neutral voltage in volts will be (1000 × 3kW) / (3 × 0.8 × 1.73A) = 722.8V.

How to Convert Volts to kW?

Similar to kW to volts conversion, here is how to convert volts to kW.  

DC Volts to kW

The power in kilowatts of a DC circuit is equal to voltage in volts times the current in amps, divided by 1000. Here's how to convert amps and volts to kW.

Formula: P (kW) = V (V) × I (A) / 1000

Example: If a DC circuit has a voltage of 50V and a current of 20A, the power will be 50V × 20A / 1000 = 1 kW. Here's another example to convert 240 volts to kW: 

P (kW) = 240V × 20A / 1000 = 4.8kW.

AC Single Phase Volts to kW

The power in kilowatts is equal to the product of current in amps, voltage in volts, the power factor, and 1000.

Formula: P (kW) = PF × V (V) × I (A) / 1000

Example: If the voltage is 5V, the current is 2A, and the power factor is 0.8, the power in kilowatts can be calculated as 0.8 × 5V × 2A / 1000 = 0.008kW.

AC Three Phase Volts to kW

If you have an AC three-phase circuit, the volts to kW conversion involves one additional factor, PF.

Formula: P (kW) = √3 × PF × I (A) ×  (V) / 1000

Example: If the input voltage is 400V, the power factor is 0.8, and the current is 10A, the power in the line-to-line voltage will be √3 × 0.8 × 10A × 400V = 5536kW.

Alternatively, the power in the line-to-neutral voltage can be calculated using the below formula.

Formula: P (kW) = 3 × PF × I (A) ×  (V) / 1000

Example: If the line-to-neutral input voltage is 40V, the power factor is 0.8, and the current is 20A, the power will be 3 × 0.8 × 20A × 40V = 1920kW.

kW to Volts FAQs

How many volts in 1kW?

In a single-phase circuit, multiply the kW by 1000 divided by the current drawn by it.

Voltage (V) = kW × 1000 / Current

You'll need to divide the formula by √3 and the power factor of 0.8 for a three-phase circuit.

Voltage (V) = kW × 1000 / √3 × Current × 0.8

In this case, we assume you have a DC circuit with one amp of current flowing through it.

Voltage = 1kW × 1000 / 1A = 1000V.

How many kW is 12V?

A 12 volt 105Ah battery has a kW value of 12V × 105Ah = 1260Wh (or 1.26kWh).

What is 1kW power?

kW or kilowatts is the unit that measures the electric power where one kilowatt is equal to 1000 watts.

How to convert kW to amps?

The Watt's Law power formula can help you convert kilowatts to amps or vice versa. According to the power formula, the current in amps equals the power indicated in watts divided by voltage in volts.

  • For a DC circuit, the kW to amps conversion formula is: I (A) = P (kW) × 1000 / V (V).
  • In the single-phase AC circuit, you'll need to consider power factor and efficiency. The formula will be: I (A) = P (kW) × 1000 / V (V) × η × PF.
  • The current draw in the wires of the three-phase system using the line-to-line voltage can be calculated as I (A) = [P (kW) × 1000] ÷ [(V) × η × PF × √3].
  • If you have a line-to-neutral voltage in a three-phase system, the current draw can be calculated as I (A) = [P (kW) × 1000] ÷ [(V) × η × PF × 3].
