How to Convert Ampere-hours to Coulombs

To convert a ampere-hour measurement to a coulomb measurement, multiply the electric charge by the conversion ratio. One ampere-hour is equal to 3,600 coulombs, so use this simple formula to convert:

coulombs = ampere-hours × 3,600

The electric charge in coulombs is equal to the ampere-hours multiplied by 3,600.

For example, here's how to convert 5 ampere-hours to coulombs using the formula above.
5 Ah = (5 × 3,600) = 18,000 C

Ampere-hours and coulombs are both units used to measure electric charge. Keep reading to learn more about each unit of measure.

Ampere-hours

One ampere-hour is the electric charge equal to the charge conveyed by a current of one ampere for one hour. One ampere-hour is equal to 3,600 coulombs.

The ampere-hour is a non-SI metric unit for electric charge. A ampere-hour is sometimes also referred to as an amp-hour. Ampere-hours can be abbreviated as Ah, for example 1 ampere-hour can be written as 1 Ah.

Coulombs

One coulomb is the electric charge equal to one ampere of current over one second.

The coulomb can be expressed as QC = IA × ts

The charge in coulombs is equal to the current in amperes times the time in seconds.

The coulomb is the SI derived unit for electric charge in the metric system. Coulombs can be abbreviated as C, for example 1 coulomb can be written as 1 C.
