Formula

Formula
mC = A·h × 3600000

Multiply any value in ampere-hours by 3600000 to obtain the value in millicoulombs.

Worked example

Convert 1 A·h to mC.

  1. 01Start with 1 A·h.
  2. 02Multiply by the conversion factor: 1 × 3600000 = 3.60000e+6 mC.
Result1 A·h = 3.60000e+6 mC

FAQ

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