Example of Ah to Wh Calculations

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.

Convert 10 Ah to Wh

To convert 10 Ah to watt-hours (Wh) with an assumed voltage of 12V:

Wh=10×12=120 Wh

Convert 100 Ah to Wh

To convert 100 Ah to watt-hours (Wh) with an assumed voltage of 12V:

Wh=100×12=1200 Wh

What Is an Ah?

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.

What Is a Wh?

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.
