To convert ampere-hours (Ah) to watt-hours (Wh), you need to understand the relationship between these two units. The formula to convert ampere-hours to watt-hours is:
Wh=Ah×V
Where V is the voltage in volts. Without a specified voltage, we will assume a common voltage of 12V for these calculations.
Below is a table showing the conversion of various ampere-hour values to watt-hours, sorted from smallest to largest, assuming a voltage of 12V.

To convert 10 Ah to watt-hours (Wh) with an assumed voltage of 12V:
Wh=10×12=120 Wh
To convert 100 Ah to watt-hours (Wh) with an assumed voltage of 12V:
Wh=100×12=1200 Wh
An ampere-hour (Ah) is a unit of electric charge. It represents the amount of electric charge transferred by a steady current of one ampere flowing for one hour. Ampere-hours are commonly used to describe the capacity of a battery, indicating how much charge it can deliver over time.
A watt-hour (Wh) is a unit of energy. It represents the amount of energy consumed or generated by a power of one watt operating for one hour. Watt-hours are commonly used to measure electrical energy consumption or generation, such as in electric utilities and battery capacities.
