## How to Convert Coulombs to Milliampere-hours

To convert a coulomb measurement to a milliampere-hour measurement, multiply the electric charge by the conversion ratio. One coulomb is equal to 0.277778 milliampere-hours, so use this simple formula to convert:

The electric charge in milliampere-hours is equal to the coulombs multiplied by 0.277778.

**For example,**here's how to convert 5 coulombs to milliampere-hours using the formula above.

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

## Coulombs

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

The coulomb can be expressed as Q_{C} = I_{A} × t_{s}

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.

## 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 can be abbreviated as *mAh*, for example 1 milliampere-hour can be written as 1 mAh.
