Full API documentation

Explanation

Formula: Milliamp-hours = Ampere-minutes × 16.667. Why: all units in this family are normalized through coulombs, including the exact identity 1 ampere-second = 1 coulomb.

Ampere-minutes (A min): a current-time charge unit equal to 60 coulombs per ampere-minute.

Milliamp-hours (mAh): a common battery-capacity unit used for phones, wearables, power banks, and small battery packs.

This route is useful when comparing battery capacity and SI charge values without mixing charge units with energy units such as Wh.

This conversion is purely multiplicative because both units reduce through coulombs using exact SI charge definitions with no offset.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.

Questions & answers

Frequently Asked Questions

How is Ampere-minutes to Milliamp-hours calculated?

The factor is derived by reducing both units to coulombs, using the exact relationship 1 amp-hour = 3600 coulombs together with fixed SI prefix scaling where needed.

Is there a reverse page for Milliamp-hours to Ampere-minutes?

Yes. Use the mirror Milliamp-hours to Ampere-minutes page to apply the inverse relationship with the same exact charge basis.

Does this Ampere-minutes to Milliamp-hours page convert charge only, not watt-hours?

Yes. Battery-charge math covers charge-to-charge units only. Converting to watt-hours also requires a voltage assumption.
