Explanation

Formula: Coulombs = Milliampere-hours × 3.6. 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.

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.

Coulombs (C): the SI unit of electric charge, defined by the exact current-time relationship 1 C = 1 A·s.

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.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Milliampere-hour = 3.6 Coulombs.
Consistency rule: calculator output and table values use the same constants and rounding policy.

Questions & answers

Frequently Asked Questions

What is 1 milliampere-hour in coulombs?

1 Milliampere-hour equals 3.6 Coulombs on this page.

Does this Milliampere-hours to Coulombs page use 1 Ah = 3600 C?

Yes. Routes that involve ampere-hours convert through the exact current-time relationship 1 Ah = 3600 C, then apply any needed SI prefix scaling.
