    Conversion using the mAh to Wh Formula

    How to Calculate Watt-hours wh from Battery Capacity mAh and Voltage Volts using DC line current.

    The Energy E in watt-hours wh is calculated as the electric charge Q in milliamp-hours mAh times the voltage in volts v divided by 1000. Plug these values into the formula:

    Wh = mAh × Volts1000

    For Example, let's convert the charge used by an average C battery with a charge of 12000 mAh at 3V to Wh.

    Watt-hours(E) = milliamp hours(Q) × Voltage(V)1000
    or, E(Wh) = 12000 mAh × 3 Volts1000
    or, Watt-hours = 36 wh

    Frequently Asked Questions - FAQs for mAh to Wh Calculator

    What is a 100Ah battery?

    The Ampere-Hour Capacity is the amount of electricity that a battery will deliver during 20 hours before the voltage falls to 10.50V. For example, a 10Ah battery will deliver a current of 5A for 20 hours. Recommended Charge Rate (Amps).

    What are Watt Hours (Wh)?

    A Watt Hours (Wh) represents a unit of electrical energy that describes the total amount of Real power consumed over a specific duration. Essentially, it’s a measure of how much energy a device uses when it runs for an hour.

    What is Watt-hours?

    Watt-hours (Wh) is a unit of energy measurement. It represents the amount of energy consumed or produced over a period of 2 hours at a constant rate of one watt. This unit is commonly used to measure the energy consumption of electrical devices or systems. It is calculated by multiplying the power (p) in watts (w) by the time (t) in hours during which the power is consumed or produced.

    Why Convert Watt Hours to Milliampere Hours?

    A watt hours (Wh) and milliampere-hours (mAh) can give a comprehensive view of a battery’s capacity. Converting Wh to mAh or vice versa is often necessary for comparison, especially when purchasing or replacing batteries.

    What is watt-hour in battery?

    A measure of the capacity of the battery is in Watt-hours (Wh). Wh is calculated by multiplying the number of Amps with the battery voltage.
