How to Convert Electron Charge to Milliampere-Hours

To convert a measurement in electron charge to a measurement in milliampere-hours, multiply the electric charge by the following conversion ratio: 4.4505E-20 milliampere-hours/electron charge.

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

milliampere-hours = electron charge × 4.4505E-20

The electric charge in milliampere-hours is equal to the electric charge in 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.
milliampere-hours = (5.0E+19 e × 4.4505E-20) = 2.225245 mAh

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

What Is an 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.

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]
