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