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.
Square Nanometer
A square nanometer (nm^2) is a unit of area equal to the area of a square with sides measuring one nanometer each.
History/Origin
The nanometer as a unit of length has been used since the development of nanotechnology in the late 20th century, with the concept of measuring extremely small areas like nm^2 emerging alongside advancements in microscopy and nanoscience.
Current Use
Square nanometers are primarily used in nanotechnology, materials science, and semiconductor industries to quantify extremely small surface areas, such as the dimensions of nanomaterials, thin films, and microscopic structures.
