How to Convert Abcoulombs to Milliampere-hours

To convert a abcoulomb measurement to a milliampere-hour measurement, multiply the electric charge by the conversion ratio. One abcoulomb is equal to 2.777778 milliampere-hours, so use this simple formula to convert:

milliampere-hours = abcoulombs × 2.777778

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

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

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


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. A 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.


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 10-3. A milliampere-hour is sometimes also referred to as a milliamp-hour. Milliampere-hours can be abbreviated as mAh, for example 1 milliampere-hour can be written as 1 mAh.

Unit of Measurement Conversion Made Easy!

There are thousands of units of measure in use across the globe, and converting from one to another can be very difficult since each conversion requires a different formula to derive the result. Our unit of measurement conversion tools are meant to be dead easy. We break the mold of the typical dry and complicated experience. In addition to converting from one measurement to another, we provide the formula so you can see how the conversion is done, use it on you’re own calculator if you need to!

Understanding the Metric System

The metric system makes it relatively easy to convert from one metric unit to another metric unit. The metric system uses a base unit, think meters or grams, and a prefix such as kilo or milli. The prefixes differ from the base units by differing powers of 10. So to convert within the metric system it’s usually a matter of multiplying or dividing by one of the powers of 10.

Here is a list of some of the common metric prefixes:

  • “kilo” – 1,000x larger
  • “hecto” – 100x larger
  • “deca” – 10x larger
  • “deci” – 10x smaller
  • “centi” – 100x smaller
  • “milli” – 1,000x smaller

There is a helpful mnemonic for remembering the prefixes: “King Henry Died Until Drinking Chocolate Milk.”
The u in Until refers to the base unit.
