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 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Today, the square perch is largely obsolete and rarely used, having been replaced by metric units such as square meters.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.
