How to Convert Milliampere-hours to Coulombs

To convert a milliampere-hour measurement to a coulomb measurement, multiply the electric charge by the conversion ratio. One milliampere-hour is equal to 3.6 coulombs, so use this simple formula to convert:

coulombs = milliampere-hours × 3.6

The electric charge in coulombs is equal to the milliampere-hours multiplied by 3.6.

For example, here's how to convert 5 milliampere-hours to coulombs using the formula above.
5 mAh = (5 × 3.6) = 18 C

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

Milliampere-hours

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 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]

Coulombs

One coulomb is the electric charge equal to one ampere of current over one second.[2]

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.
