    How to use the Wh to kWh Converter

    1. Type a value in the Watt-Hours box. The kilowatt-hours result appears instantly.
    2. Going the other way? Type in the Kilowatt-hours 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.

    Watt-Hours to kilowatt-hours formula

    kWh = Wh ÷ 1000
    1. Take the value in watt-hours.
    2. Divide it by 1000 (the number of watt-hours in one kilowatt-hour).

    Example: 100 Wh ÷ 1000 = 0.1 kWh.

    Reverse formula (kilowatt-hours to watt-hours): Wh = kWh × 1000. Example: 0.074 kWh × 1000 = 74 Wh.

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

    About watt-Hours and kilowatt-hours

    Watt-Hours (Wh). A watt-hour (Wh) is the energy of one watt used for one hour, 3,600 joules. Laptop and power-bank batteries are rated in Wh; airlines allow batteries up to 100 Wh in carry-on bags.

    Kilowatt-hours (kWh). A kilowatt-hour is the energy used by a 1,000-watt device running for one hour, 3.6 million joules. Electricity bills are charged per kWh.

    Frequently asked questions

    How many kilowatt-hours in 1 watt-hour?

    One watt-hour equals 0.001 kilowatt-hours. Looking at it the other way, one kilowatt-hour is 1,000 watt-hours.

    How do you convert watt-hours to kilowatt-hours?

    Divide the number of watt-hours by 1000. For example, 100 Wh ÷ 1000 = 0.1 kWh.

    What is 74 watt-hours in kilowatt-hours?

    74 Wh is 0.074 kWh (20,000 mAh power bank).

    How do I convert kilowatt-hours back to watt-hours?

    Multiply by 1000, or press the ⇄ swap button above. For example, 0.074 kWh × 1000 = 74 Wh.

    Is a kWh the same as a kW?

    No. kW is power (how fast energy is used) and kWh is energy (power × time). A 2 kW heater running for 3 hours uses 6 kWh.

    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.

    Are all the tools on FreeToolCabin tested for quality and accuracy?
