Milliamp-hours to Coulombs
1 Milliamp-hour = 3.6 Coulombs · fixed factor via exact coulomb-based charge definitions · no offset
Direct Answer
1 Milliamp-hour equals 3.6 Coulombs
This conversion uses a fixed factor based on exact coulomb-based charge definitions.
For 10 Milliamp-hours, the result equals 36 Coulombs.

SwitchExplanation
Formula: Coulombs = Milliamp-hours × 3.6. Why: SI charge units such as coulombs and their prefixes are exact, so the calculator normalizes through coulombs before applying the target battery-charge unit.
Milliamp-hours (mAh): a common battery-capacity unit used for phones, wearables, power banks, and small battery packs.
Coulombs (C): the SI unit of electric charge.
This route is useful when translating battery-style capacity values into SI charge units for engineering, calculation, and reference work.
This conversion is purely multiplicative because both units reduce through coulombs using exact SI charge definitions with no offset.

Frequently Asked Questions
How is Milliamp-hours to Coulombs 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 Coulombs to Milliamp-hours?
Yes. Use the mirror Coulombs to Milliamp-hours page to apply the inverse relationship with the same exact charge basis.
Does this Milliamp-hours to Coulombs page convert charge only, not watt-hours?
Yes. This page converts charge-to-charge units only. Converting to watt-hours also requires a voltage assumption.
