How to Convert Ampere-Hours to Coulombs
To convert from ampere-hours (Ah) to coulombs (C), you multiply the charge in ampere-hours by 3,600. For more information about ampere-hours as a unit of measurement, visit our amperes-hour page.
Formula
Coulombs = Ampere-Hours × 3,600
or
C = Ah × 3,600
Examples
- 1 Ah = 1 × 3,600 = 3,600 C
- 10 Ah = 10 × 3,600 = 36,000 C
- 100 Ah = 100 × 3,600 = 360,000 C
- 1,000 Ah = 1,000 × 3,600 = 3,600,000 C
When to Convert Ampere-Hours to Coulombs
This conversion is useful in electrical engineering and battery technology, as ampere-hours are commonly used to express battery capacity.
Battery Capacity
Battery manufacturers often specify capacity in ampere-hours, so this conversion helps in understanding the total charge stored in coulombs.
Power Systems
In power system design, converting between coulombs and ampere-hours helps in calculating energy storage and discharge rates.

Frequently Asked Questions
What is an ampere-hour (Ah)?
An ampere-hour is a unit of electric charge, commonly used to express the capacity of batteries. One ampere-hour is equal to 3,600 coulombs.
What is a coulomb (C)?
The coulomb is the SI unit of electric charge, defined as the amount of charge transported by a constant current of one ampere in one second.
How do I convert coulombs to ampere-hours?
To convert from coulombs to ampere-hours, you divide the charge in coulombs by 3,600. For example, 3,600 C is equal to 3,600 / 3,600 = 1 Ah.
