    2. Going the other way? Type in the Kilowatts box, or press the ⇄ swap button.
    3. Set the precision with the decimal places menu and adjust the options to match your situation.
    4. Check the working in the step-by-step box, then press Copy result or click any row in the tables below.

    Kilovolt-amperes to kilowatts formula

    kW = kVA × PF
    1. Take the apparent power in kVA.
    2. Multiply by the power factor (between 0 and 1).

    Example: 10 kVA × 0.8 = 8 kW.

    Reverse formula: kVA = kW ÷ PF. Example: 4 kW ÷ 0.8 = 5 kVA.

    Generators are usually rated at a power factor of 0.8, so a 10 kVA generator supplies about 8 kW of real power.

    About kilovolt-amperes and kilowatts

    Kilovolt-amperes (kVA). Kilovolt-amperes (kVA) measure apparent power: voltage × current, regardless of the power factor. Generators, UPSs and transformers are rated in kVA.

    Kilowatts (kW). The kilowatt is 1,000 watts. Engines, motors, heaters and EV chargers are rated in kW.

    Frequently asked questions

    How do you convert kVA to kW?

    Multiply the kVA by the power factor: kW = kVA × PF. With a typical generator rating of PF 0.8, 10 kVA = 8 kW.

    What is the difference between kVA and kW?

    kVA is apparent power (volts × amps); kW is real power, the part that does work. They are equal only when the power factor is 1.

    What power factor should I use?

    Use the value on the equipment label. Generators and UPSs are commonly rated at 0.8; motors at full load run around 0.8 to 0.9; heaters are about 1.

    What is kVAR?

    kVAR is reactive power. kVA² = kW² + kVAR², so it is shown under the result too.

    What is 15 kilovolt-amperes in kilowatts?

    15 kVA is 12 kW. This assumes a power factor of 0.8.

    Is this converter free and private?

    Yes. It is free with no sign-up, and every calculation runs in your browser, so nothing you type is sent to a server.
