Formula
Formula
C = mA·h × 3.6
Multiply any value in milliampere-hours by 3.6 to obtain the value in coulombs.
Worked example
Convert 1000 mA·h to C.
- 01Start with 1000 mA·h.
- 02Multiply by the conversion factor: 1000 × 3.6 = 3600 C.
Result1000 mA·h = 3600 C

FAQ
What is the conversion factor from mA·h to C?
1 mA·h equals 3.6 C. To convert, multiply the value in milliampere-hours by 3.6.
How do I convert 1 mA·h to C?
1 mA·h = 3.6 C. For any value, multiply by 3.6.
How do I convert C back to mA·h?
Divide by the same factor — or equivalently, multiply by 0.2777778. So 1 C = 0.277778 mA·h.
When would I need to convert milliampere-hour to coulomb?
Electric-charge conversions between mA·h and C 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 mA·h and C are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
