What Is an Ampere-Hour?

An ampere-hour is a unit used to measure electric charge.

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]

How Much 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.

How to Convert Ampere-Hours

To convert ampere-hours to another unit of electric charge, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.[2]

You can find the conversion factors for ampere-hours in the conversion table below.

Then, multiply the electric charge measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

ampere-hours × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
