Milliamp Hours to Amp Hours (mAh to Ah) Converter
Convert milliamp hours (mAh) to amp hours (Ah).
Milliamp Hours (mAh) to Amp Hours (Ah) Conversion
To convert milliamp hours (mAh) to amp hours (Ah), you can use the following formula:
Conversion Formula ⚡
The formula becomes:
Ah = mAh / 1000Where:
- Ah = Charge in amp hours (Ah)
- mAh = Charge in milliamp hours (mAh)
Key Insight:
This formula is essential for converting battery capacity from milliamp hours to amp hours, which is a more standard unit of measurement.
🤔 What Do These Terms Really Mean?
Let’s break down these electrical measurements in a way that’s easy to understand:
📊 Milliamp Hours (mAh)
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
⚡ Amp Hours (Ah)
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
🎯 Quick Memory Trick
Remember: 1 Ah = 1000 mAh
Just like:
- 1 meter = 1000 millimeters
- 1 liter = 1000 milliliters
The ‘milli’ prefix always means one-thousandth!

Milliampere-Hour to Ampere-Hour Conversion FAQs
To convert from Milliampere-Hours to Ampere-Hours, use the formula:
Where:
- Ah = Charge in ampere-hours (Ah)
- mAh = Charge in milliampere-hours (mAh)
This formula accounts for the conversion of milliampere-hours to ampere-hours by dividing by 1000.
This conversion is useful when you need to determine the capacity of a battery or capacitor based on its charge in milliampere-hours.
Common capacity values can be expressed in ampere-hours (Ah) and milliampere-hours (mAh). For example:
- A “2000mAh” battery would be:
This notation is commonly used in battery specifications and capacity calculations.
