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.
Circular Mil
A circular mil is a unit of area used to measure the cross-sectional size of wires, representing the area of a circle with a diameter of one mil (one thousandth of an inch).
History/Origin
The circular mil originated in the electrical industry to specify wire sizes before the adoption of metric units. It has been a standard measurement in North America for wire gauge sizes for many decades.
Current Use
Circular mils are still used today in the electrical industry to specify wire cross-sectional areas, especially in North America, although metric units are increasingly common.
