Milliamp Hours (mAh) to Amp Hours (Ah) Conversion

To convert milliamp hours (mAh) to amp hours (Ah), you can use the following formula:

The formula becomes:

Ah = mAh / 1000

Where:

This formula is essential for converting battery capacity from milliamp hours to amp hours, which is a more standard unit of measurement.

Think of mAh as tiny buckets of electrical charge:

Scientific Definition: One milliamp hour represents the amount of energy charge transferred by a steady current of one milliampere flowing for one hour
Real-world Example: A smartphone with a 3000 mAh battery can theoretically provide 3000 milliamps of current for one hour, or 1000 milliamps for three hours
Common Usage: Most portable devices like phones, tablets, and wireless earbuds use mAh ratings

Think of Ah as larger buckets of electrical charge:

Scientific Definition: One amp hour equals the amount of energy charge transferred by a steady current of one ampere flowing for one hour
Real-world Example: A car battery rated at 50 Ah can theoretically deliver 50 amperes for one hour, or 5 amperes for 10 hours
Common Usage: Larger batteries like those in cars, solar systems, and industrial equipment use Ah ratings
