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 Pole
A square pole is a unit of area measurement representing the area of a square with one pole (perch) as its side, where one pole equals 16.5 feet, making the area 272.25 square feet.
History/Origin
The square pole originated from traditional land measurement systems used in England and colonial America, primarily for measuring plots of land in rural and agricultural contexts before the widespread adoption of metric units.
Current Use
Today, the square pole is rarely used in modern measurement systems but may still be encountered in historical land records, rural property descriptions, or in regions that retain traditional measurement units.
