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.
Current Use
Today, the square perch is largely obsolete and rarely used, having been replaced by metric units such as square meters. It may still be encountered in historical land records or in regions where traditional units persist.
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.
