How to Convert Nanocoulombs to Milliampere-hours

To convert a nanocoulomb measurement to a milliampere-hour measurement, divide the electric charge by the conversion ratio.

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

milliampere-hours = nanocoulombs ÷ 3,600,000,000

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

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

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


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

The nanocoulomb is a multiple of the coulomb, which is the SI derived unit for electric charge. In the metric system, "nano" is the prefix for 10-9. Nanocoulombs can be abbreviated as nC; for example, 1 nanocoulomb can be written as 1 nC.


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 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]
