First of all, to perform ampere hours to watt hours conversion, you need to have an in-depth understanding of the concepts of ampere hours and watt hours, which will help you understand the ampere hours to watt hours calculator formula faster.

2. Ampere-hour

An ampere hour is a unit of electricity, represented by the symbol Ah. As an example, 1Ah refers to the amount of charge that passes through a cross-section of a conductor at a constant current of 1A in one hour. Ampere hours are often used to indicate the capacity of a battery, and you can easily find the key parameters of this battery from the battery’s instruction manual, for example, a 6 Ampere hour battery can be discharged for 1 hour at a current of 6A.

2. Watt-hour

The watt-hour is a unit of energy, denoted by the symbol Wh, which is used to express the amount of work done or the amount of energy converted in a given period of time. As an example, a 200Wh Li-FePO4 battery indicates that the Li-FePO4 battery can run at 100Watt for one hour.

After understanding the specific meaning of the above two data, you need to know that the conversion of ampere hours to watt hours requires a key data – voltage, voltage refers to the potential difference between two points, denoted by the symbol V, which is the force that pushes the charge to move directionally in an electric circuit. Many devices operate with a voltage rating; for example, you can find the voltage rating of a battery in its instruction manual.

With these two key figures, voltage (V) and ampere-hours (Ah), you can make the conversion from ampere-hours to watt-hours, which is based on the formula:

Wh= Ah x V

For example, suppose your LiFePO4 battery has a capacity of 6Ah and the rated voltage of the battery is 12V, then you can use the Ampere-hour to Watt-hour Calculator to input these two data into the corresponding position, and then according to the above formula, you can know that your LiFePO4 battery can run for one hour at a power of 72watt.

Of course, the principle of Ampere-hour to Watt-hour calculation can be distorted, that is,

Ah = Wh/ V

For example, suppose you only know the rated voltage (assuming 12V) and watt-hour (assuming 60Wh) of your LiFePO4 battery, and you want to know the capacity of your LiFePO4 battery, you can make use of the deformation of the formula in the Ampere-hour (Ah) = Watt-hour (Wh) / Voltage (V), and substitute the data into the data to get the capacity of your LiFePO4 battery is 5Ah. The capacity of your LiFePO4 battery is 5Ah.

Therefore, as long as you know any two data in Ampere-hour, Watt-hour and Voltage, you can get another data, which can be very convenient for you to calculate the relevant data of your equipment.

3. Summary

Ampere-hour to Watt-hour calculation is a commonly used formula for devices, especially for energy storage devices like batteries, through the in-depth mastery of this formula, you can further deepen the understanding of your batteries, of course, the Ampere-hour to Watt-hour Calculator can save you a lot of time and energy, and allow you to get the accurate data quickly, which can be a big help in your life.
