Explanation

Formula: Milliampere-hours = Ampere-hours × 1,000. 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.

Ampere-hours (Ah): a larger electric-charge unit commonly used for battery capacity because it expresses current delivered over time.

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 mainly useful when switching between battery-capacity style units and standard SI charge units while keeping the same physical quantity.

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