Explanation

Formula: Milliampere-hours = Millicoulombs × 0.000278. Why: ampere-hour units convert to charge through current over time, with 1 Ah = 3600 C exactly and 1 mAh = 3.6 C exactly, while coulomb-prefixed units scale by exact powers of ten.

Millicoulombs (mC): an SI-prefixed electric-charge unit equal to one thousandth of a coulomb.

Milliampere-hours (mAh): a battery-scale electric-charge unit equal to one thousandth of an ampere-hour, commonly used for small batteries and portable electronics.

This route is useful when converting very small SI charge quantities into battery-capacity style units while keeping the same underlying electric charge.

This conversion is purely multiplicative with no offset because both units reduce exactly to coulombs under the same electric-charge model.
