## How to Convert Ampere-hours to Milliampere-hours

To convert an ampere-hour measurement to a milliampere-hour measurement, multiply the electric charge by the conversion ratio. One ampere-hour is equal to 1,000 milliampere-hours, so use this simple formula to convert:

The electric charge in milliampere-hours is equal to the ampere-hours multiplied by 1,000.

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

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

## Ampere-hours

One ampere-hour is the electric charge equal to the charge conveyed by a current of one ampere for one hour. One ampere-hour is equal to 3,600 coulombs.

The ampere-hour is a non-SI metric unit for electric charge. A ampere-hour is sometimes also referred to as an amp-hour. Ampere-hours are usually abbreviated as *Ah*, although the formally adopted expression is *A·h*. The abbreviation *A h* is also sometimes used. For example, 1 ampere-hour can be written as 1 Ah, 1 A·h, or 1 A 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]}

## 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.
