What Is a Millicoulomb?
A millicoulomb is a unit of electric charge equal to 1/1,000 of a coulomb (0.001 C). One-thousandth of a Coulomb. [1]
The millicoulomb is classified as a metric and SI-compatible unit of electric charge. Millicoulombs can be abbreviated as mC; for example, 1 millicoulomb can be written as 1 mC.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millicoulomb (mC) a convenient decimal multiple of the coulomb (C).
In practice, millicoulombs (mC) are widely used across fine-tolerance laboratory, analytical, and micro-scale electric charge measurements within SI metric workflows, engineering documentation, and technical data sheets.
What Is a Milliampere-hour?
A milliampere-hour is a unit of electric charge equal to 3.6 coulombs (C), the base unit for electric charge. Battery capacity unit equal to 0.001 Ah or 3.6 Coulombs. [2]
The milliampere-hour is classified as a standard unit of electric charge. Milliampere-hours can be abbreviated as mAh; for example, 1 milliampere-hour can be written as 1 mAh.
In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the milliampere-hour (mAh) a convenient decimal multiple of the coulomb (C).
In practice, milliampere-hours (mAh) are widely used across standard electric charge applications within international standard workflows, engineering documentation, and technical data sheets.
When converting electric charge between millicoulombs (mC) and milliampere-hours (mAh), keep full floating-point precision (1 mC = 0.000277778 mAh; 1 mAh = 3,600 mC) during intermediate calculations and round only the final milliampere-hour figure to match your instrument tolerance.
