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

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

Since one ampere-hour is equal to 1,000 milliampere-hours, you can use this simple formula to convert:

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

**For example,**here's how to convert 500 milliampere-hours to ampere-hours using the formula above.

Milliampere-hours and ampere-hours 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]}

## 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. An 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.
