Ampere per Circular Mil
A/circular mil
Definition
The Ampere per Circular Mil (A/circular mil) is a unit of surface current density equal to approximately 1.97 billion amperes per square meter. A circular mil is the area of a circle with a diameter of one mil (0.001 inch), commonly used in wire and cable specifications.
History/Origin
The circular mil was established as a standard unit for wire cross-sectional area in electrical engineering. This unit became important when precise current density calculations were needed for wire sizing, cable design, and electrical conductor specifications in early electrical systems.
Current Use
Ampere per circular mil is primarily used in wire and cable manufacturing, electrical conductor design, and power distribution systems. It is essential for determining current carrying capacity and ensuring proper wire sizing for electrical installations and equipment.

Abampere per Square Centimeter
abA/cm²
Definition
The Abampere per Square Centimeter (abA/cm²) is a CGS electromagnetic unit of surface current density, equivalent to 100,000 amperes per square meter. It is part of the absolute electromagnetic system of units, which defines electrical quantities based on magnetic phenomena without arbitrary constants.
History/Origin
The abampere per square centimeter emerged from the CGS electromagnetic system, which was prevalent in scientific research during the late 19th and early 20th centuries. This system provided a coherent framework for understanding electromagnetism before the SI system became the international standard.
Current Use
The abampere per square centimeter is largely obsolete in modern practical applications. Its primary relevance is in academic studies of classical electromagnetism, historical physics literature, and in specialized theoretical contexts where CGS units are still used for consistency with older formulations.
