How to Convert Abcoulombs to Ampere-Hours

To convert a measurement in abcoulombs to a measurement in ampere-hours, divide the electric charge by the following conversion ratio: 360 abcoulombs/ampere-hour.

Since one ampere-hour is equal to 360 abcoulombs, you can use this simple formula to convert:

ampere-hours = abcoulombs ÷ 360

The electric charge in ampere-hours is equal to the electric charge in abcoulombs divided by 360.

For example, here's how to convert 500 abcoulombs to ampere-hours using the formula above.
ampere-hours = (500 abC ÷ 360) = 1.388889 Ah

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

What Is an Abcoulomb?

One abcoulomb is the electric charge equal to one abampere of current over one second, or ten coulombs.

The abcoulomb is a centimeter-gram-second (CGS) electromagnetic unit of electric charge. An abcoulomb is sometimes also referred to as an EMU. Abcoulombs can be abbreviated as abC, and are also sometimes abbreviated as aC. For example, 1 abcoulomb can be written as 1 abC or 1 aC.

What Is an Ampere-Hour?

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. 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.[1]
