## How to Convert Millicoulombs to Ampere-hours

To convert a millicoulomb measurement to an ampere-hour measurement, divide the electric charge by the conversion ratio. One ampere-hour is equal to 3,600,000 millicoulombs, so use this simple formula to convert:

The electric charge in ampere-hours is equal to the millicoulombs divided by 3,600,000.

**For example,**here's how to convert 5,000,000 millicoulombs to ampere-hours using the formula above.

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

## Millicoulombs

The millicoulomb is 1/1,000 of a coulomb, which is the electric charge equal to one ampere of current over one second.

The millicoulomb is a multiple of the coulomb, which is the SI derived unit for electric charge. In the metric system, "milli" is the prefix for 10^{-3}. Millicoulombs can be abbreviated as *mC*, for example 1 millicoulomb can be written as 1 mC.

## 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]}
