What are Circular Mil and Square Inch

A circular mil is a unit of area used primarily in the United States to define the cross-sectional size of a wire or a cable. It represents the area of a circle with a diameter of one-thousandth of an inch, or one mil. Since it's a measure of a circular area, it’s particularly useful in applications where the circular geometry is integral, such as electrical wiring.

A square inch is a common unit of area measurement in the United States and the United Kingdom. It is defined as the area of a square with each side being one inch in length. One square inch is equal to 6.4516 square centimeters. This unit is widely used in construction, manufacturing, and engineering for measuring surface areas of various materials.

History of Circular Mil and Square Inch

The concept of the circular mil dates back to when electrical conductors were being standardized. The circular mil was developed as a convenient method for describing wire sizes because it represented the area directly proportional to the weight and resistance of the wire. This concept was later adapted for conversion to square inches for broader applications in engineering and manufacturing.
