How to Convert Microcoulombs to Ampere-hours

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

Since one ampere-hour is equal to 3,600,000,000 microcoulombs, you can use this simple formula to convert:

ampere-hours = microcoulombs ÷ 3,600,000,000

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

For example, here's how to convert 5,000,000,000 microcoulombs to ampere-hours using the formula above.
5,000,000,000 μC = (5,000,000,000 ÷ 3,600,000,000) = 1.388889 Ah

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


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

The microcoulomb is a multiple of the coulomb, which is the SI derived unit for electric charge. In the metric system, "micro" is the prefix for 10-6. Microcoulombs can be abbreviated as μC; for example, 1 microcoulomb can be written as 1 μC.


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]
