How to Convert Abcoulombs to Milliampere-Hours

To convert a measurement in abcoulombs to a measurement in milliampere-hours, multiply the electric charge by the following conversion ratio: 2.777778 milliampere-hours/abcoulomb.

Since one abcoulomb is equal to 2.777778 milliampere-hours, you can use this simple formula to convert:

milliampere-hours = abcoulombs × 2.777778

The electric charge in milliampere-hours is equal to the electric charge in abcoulombs multiplied by 2.777778.

For example, here's how to convert 5 abcoulombs to milliampere-hours using the formula above.
milliampere-hours = (5 abC × 2.777778) = 13.888889 mAh

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 a Milliampere-Hour?

One milliampere-hour is the electric charge equal to the charge conveyed by a current of one milliampere for one hour. One milliampere-hour is equal to 3.6 coulombs.

The milliampere-hour is a non-SI metric unit for electric charge. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliampere-hour is sometimes also referred to as a milliamp-hour. Milliampere-hours are usually abbreviated as mAh, although the formally adopted expression is mA·h. The abbreviation mA h is also sometimes used. For example, 1 milliampere-hour can be written as 1 mAh, 1 mA·h, or 1 mA 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]
