Square Millimeter
A square millimeter (mm²) is a unit of area equal to the area of a square with sides measuring one millimeter.
History/Origin
The square millimeter has been used in scientific and engineering contexts for precise measurement of small areas, especially in fields like electronics and material science, as a subdivision of the metric system established in the 19th century.
Current Use
It is commonly used today in fields such as electronics, manufacturing, and scientific research to measure small surface areas, including the cross-sectional areas of wires and components.
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.
