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.


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.
