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.
Barn
A barn is a unit of area used primarily in agriculture to measure land, especially for farming purposes.
History/Origin
The barn originated as a unit of measure in the 19th century, based on the amount of land that could be covered by a barn, roughly equivalent to 40 square rods or about 40 acres, and was used in land surveying and farming contexts.
Current Use
Today, the barn is largely obsolete as a formal measurement unit but is still used colloquially in agriculture to refer to land area, especially in the United States, often informally approximating 40 acres.
