Milliampere-Hours to Abcoulombs Converter

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]

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.
