Ampere-hours to Coulombs Conversion
Enter the electric charge in ampere-hours below to get the value converted to coulombs.
How to Convert Ampere-hours to Coulombs
To convert an ampere-hour measurement to a coulomb measurement, multiply the electric charge by the conversion ratio.
Since one ampere-hour is equal to 3,600 coulombs, you can use this simple formula to convert:
The electric charge in coulombs is equal to the ampere-hours multiplied by 3,600.
How Many Coulombs are in an Ampere-hour?
There are 3,600 coulombs in an ampere-hour, which is why we use this value in the formula above.
1 Ah = 3,600 C
Ampere-hours and coulombs are both units used to measure electric charge. Keep reading to learn more about each unit of measure.
The ampere-hour is a non-SI metric unit for electric charge. An ampere-hour is sometimes also referred to as an amp-hour. Ampere-hours are usually abbreviated as Ah, although the formally adopted expression is A·h. The abbreviation A h is also sometimes used. For example, 1 ampere-hour can be written as 1 Ah, 1 A·h, or 1 A h.
In formal expressions, the centered dot (·) or space is used to separate units used to indicate multiplication in an expression and to avoid conflicting prefixes being misinterpreted as a unit symbol.
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.
