Formula
Formula
mA·h = A·h × 1000
Multiply any value in ampere-hours by 1000 to obtain the value in milliampere-hours.
Worked example
Convert 1 A·h to mA·h.
- 01Start with 1 A·h.
- 02Multiply by the conversion factor: 1 × 1000 = 1000 mA·h.
Result1 A·h = 1000 mA·h

FAQ
What is the conversion factor from A·h to mA·h?
1 A·h equals 1000 mA·h. To convert, multiply the value in ampere-hours by 1000.
How do I convert 1 A·h to mA·h?
1 A·h = 1000 mA·h. For any value, multiply by 1000.
How do I convert mA·h back to A·h?
Divide by the same factor — or equivalently, multiply by 0.001. So 1 mA·h = 0.001 A·h.
When would I need to convert ampere-hour to milliampere-hour?
Electric-charge conversions between A·h and mA·h appear in battery capacity specification (A·h, mA·h), electroplating and electrochemistry (coulombs of charge transferred), and capacitor energy calculations. 1 A·h is exactly 3600 C — the conversion is a linear factor and does not depend on voltage, current profile or chemistry.
Is the conversion exact?
Yes. Both A·h and mA·h are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
