Ampere-seconds to Coulombs
Snapshot
1 Ampere-second equals 1 Coulomb. Conversion Encyclopedia uses the same fixed conversion basis across the calculator, common values, and reverse page for this page.
- Reference basis: This conversion uses a fixed factor based on exact coulomb-based charge definitions.
- Example: For 10 Ampere-seconds, the result equals 10 Coulombs.
- Use the reverse page if you need the opposite direction with the same basis.

SwitchExplanation
Formula: Coulombs = Ampere-seconds × 1. 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.
Ampere-seconds (A s): a current-time charge unit exactly equal to coulombs.
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 Ampere-seconds to Coulombs calculated?
The factor is derived by reducing both units to coulombs, using the exact current-time relationships 1 ampere-second = 1 coulomb and 1 ampere-minute = 60 coulombs where relevant.
Is there a reverse page for Coulombs to Ampere-seconds?
Yes. Use the mirror Coulombs to Ampere-seconds page to apply the inverse relationship with the same exact charge basis.
Can I use decimal values for Ampere-seconds to Coulombs?
Yes. Decimal inputs are supported for Ampere-seconds to Coulombs, and the same exact coulomb-based normalization is used throughout the page.
