    How to use the Watts to kW Converter

    1. Type a value in the Watts box. The kilowatts result appears instantly.
    2. Going the other way? Type in the Kilowatts box, or press the ⇄ swap button.
    3. Set the precision with the decimal places menu.
    4. Check the working in the step-by-step box, then press Copy result or click any row in the tables below.

    Watts to kilowatts formula

    kW = W ÷ 1000
    1. Take the value in watts.
    2. Divide it by 1000 (the number of watts in one kilowatt).

    Example: 1,000 W ÷ 1000 = 1 kW.

    Reverse formula (kilowatts to watts): W = kW × 1000. Example: 1.5 kW × 1000 = 1,500 W.

    The factor is a whole number (1000), so this one is easy to do in your head or with long division.
