Millicoulombs to Ampere-Hours Converter

What Is a Millicoulomb?

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

The millicoulomb is a multiple of the coulomb, which is the SI derived unit for electric charge. In the metric system, "milli" is the prefix for thousandths, or 10^-3. Millicoulombs can be abbreviated as mC; for example, 1 millicoulomb can be written as 1 mC.

What 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.

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]
