Square Mile (Us Survey)
A square mile (US survey) is a unit of area equal to the area of a square with sides of one mile, specifically used in the United States survey system.
History/Origin
The square mile has been used historically in land measurement and mapping in the United States, originating from the British imperial system. It is commonly employed in surveying and land division, especially in rural and agricultural contexts.
Current Use
Today, the square mile (US survey) is primarily used in land surveying, real estate, and geographic data within the United States, particularly for measuring large land areas such as counties, states, and national parks.
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.
