FAQ
What is the conversion factor from A·h to μC?
1 A·h equals 3.6e+9 μC. To convert, multiply the value in ampere-hours by 3.6e+9.
How do I convert 1 A·h to μC?
1 A·h = 3.6e+9 μC. For any value, multiply by 3.6e+9.
How do I convert μC back to A·h?
Divide by the same factor — or equivalently, multiply by 2.777778e-10. So 1 μC = 2.77778e-10 A·h.
When would I need to convert ampere-hour to microcoulomb?
Electric-charge conversions between A·h and μC 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 μC are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
