Square Micrometer
A square micrometer (µm²) is a unit of area equal to the area of a square with sides measuring one micrometer (µm).
History/Origin
The square micrometer originated with the development of the metric system and microscopic measurement techniques, becoming standard in scientific fields requiring precise area measurements at microscopic scales.
Current Use
The square micrometer is used in fields such as microbiology, materials science, and nanotechnology to measure tiny surface areas, particle sizes, and microscopic features.
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.
