Ampere-hours to Coulombs
Snapshot
1 Ampere-hour equals 3,600 Coulombs. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.
- Reference basis: This conversion uses exact coulomb-based electric charge definitions.
- Example: For 0.001 Ampere-hours, the result equals 3.6 Coulombs.
- Use the reverse page if you need the opposite direction with the same basis.

SwitchExplanation
This page answers the core electric-charge question directly: 1 ampere-hour equals 3600 coulombs exactly. The reason is that 1 coulomb is 1 ampere-second, and 1 hour contains 3600 seconds, so 1 Ah = 1 A x 3600 s = 3600 C.
Use this converter when battery capacity is written in ampere-hours but you need the equivalent charge in coulombs. Because the relationship is exact, the same fixed factor works for small values like 0.001 Ah and larger values like 10 Ah or 100 Ah without any offset or approximation.

Frequently Asked Questions
What is 1 ampere-hour in coulombs?
1 Ampere-hour equals 3,600 Coulombs on this page.
Does this Ampere-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.
When would I convert ampere-hours to coulombs?
This route is mainly useful when switching between battery-capacity style units and standard SI charge units while keeping the same physical quantity.
How do I reverse Ampere-hours to Coulombs?
Use the mirror Coulombs to Ampere-hours route; it applies the inverse relationship with the same electric-charge assumptions.
