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.

Ampere per Square Mil
A/mi²
Definition
The Ampere per Square Mil (A/mi²) is a unit of surface current density equal to approximately 1.55 billion amperes per square meter. A square mil is equal to one millionth of a square inch, making this unit extremely fine-grained for measuring current density in very small areas or thin films.
History/Origin
The square mil was commonly used in early electrical engineering, particularly in wire gauge specifications and thin-film applications. This unit emerged when precise measurements of current density in very small areas became important for electronic component design and manufacturing.
Current Use
Ampere per square mil is primarily used in specialized applications involving very thin conductors, microelectronics, and precision electrical measurements where extremely small surface areas are involved. It is particularly relevant in semiconductor manufacturing and thin-film technology.
