FAQ
What is the conversion factor from mC to A·h?
1 mC equals 2.777778e-7 A·h. To convert, multiply the value in millicoulombs by 2.777778e-7.
How do I convert 1 mC to A·h?
1 mC = 2.77778e-7 A·h. For any value, multiply by 2.777778e-7.
How do I convert A·h back to mC?
Divide by the same factor — or equivalently, multiply by 3600000. So 1 A·h = 3.60000e+6 mC.
When would I need to convert millicoulomb to ampere-hour?
Electric-charge conversions between mC and A·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 mC and A·h are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
