Circular Inch
A circular inch is a unit of area measurement representing the area of a circle with a diameter of one inch.
History/Origin
The circular inch originated as a specialized measurement in fields requiring precise circular area calculations, but it is not widely used in standard measurement systems and has limited historical adoption.
Current Use
Today, the circular inch is primarily used in niche applications such as engineering and manufacturing where circular area measurements are relevant, but it remains a rarely used unit outside specialized contexts.
Square Mil
A square mil is a unit of area equal to the area of a square with sides measuring one mil (thousandth of an inch).
History/Origin
The square mil has been used primarily in engineering and manufacturing to measure very small areas, especially in fields like electronics and materials science, where precision at a microscopic scale is required.
Current Use
Today, the square mil is mainly used in the electronics industry to specify the cross-sectional area of wires and conductors, as well as in materials science for measuring tiny surface areas.
