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.
Circular Inch
A circular inch is a unit of area measurement representing the area of a circle with a diameter of one inch.
History/Origin
The circular inch originated as a specialized measurement in fields requiring precise circular area calculations, but it is not widely used in standard measurement systems and has limited historical adoption.
Current Use
Today, the circular inch is primarily used in niche applications such as engineering and manufacturing where circular area measurements are relevant, but it remains a rarely used unit outside specialized contexts.
