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.
Square Perch
A square perch is a unit of area measurement equal to the area of a square with one perch (16.5 feet) on each side.
History/Origin
The square perch, also known as a square rod or perche, originated in the British Imperial system and was traditionally used in land measurement, especially in the UK and former British colonies.
