How to Convert Microcoulombs to Milliampere-Hours

To convert a measurement in microcoulombs to a measurement in milliampere-hours, divide the electric charge by the following conversion ratio: 3,600,000 microcoulombs/milliampere-hour.

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

milliampere-hours = microcoulombs ÷ 3,600,000

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

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

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

What Is a Microcoulomb?

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 millionths, or 10-6. Microcoulombs can be abbreviated as μC; for example, 1 microcoulomb can be written as 1 μC.

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.

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]
