Milliampere-hours to Coulombs Conversion

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.^[1]

Coulombs

One coulomb is the electric charge equal to one ampere of current over one second.^[2]

The coulomb can be expressed as Q_C = I_A × t_s

The charge in coulombs is equal to the current in amperes times the time in seconds.

The coulomb is the SI derived unit for electric charge in the metric system. Coulombs can be abbreviated as C, for example 1 coulomb can be written as 1 C.
