Hint: use a scientific notation calculator to convert E notation to decimal

## How to Convert Microcoulombs to Milliampere-hours

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

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 microcoulombs divided by 3,600,000.

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

## Microcoulombs

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.

## Milliampere-hours

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.
