## How to Convert Electron Charge to Milliampere-hours

To convert an electron charge measurement to a milliampere-hour measurement, multiply the electric charge by the conversion ratio.

Since one electron charge is equal to 4.4505E-20 milliampere-hours, you can use this simple formula to convert:

The electric charge in milliampere-hours is equal to the electron charge multiplied by 4.4505E-20.

**For example,**here's how to convert 5.0E+19 electron charge to milliampere-hours using the formula above.

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

## Electron Charge

Electron charge is equal to the charge of an electron, and is the inverse of elementary charge, which is the magnitude of the charge of a proton. It is equal to 1.602176634×10−19 coulombs, per the 2019 SI redefinition of the coulomb.

Electron charge can be abbreviated as *e*; for example, 1 electron charge can be written as 1 e.

## 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]}
