To convert a measurement in ampere-hours to a measurement in milliampere-hours, multiply the electric charge by the following conversion ratio: 1,000 milliampere-hours/ampere-hour.

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

milliampere-hours = ampere-hours × 1,000

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

For example, here's how to convert 5 ampere-hours to milliampere-hours using the formula above.
milliampere-hours = (5 Ah × 1,000) = 5,000 mAh

How Many Milliampere-Hours Are in an Ampere-Hour?

There are 1,000 milliampere-hours in an ampere-hour, which is why we use this value in the formula above.

1 Ah = 1,000 mAh

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

What Is an Ampere-Hour?

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.

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]

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.
