Square Chain
A square chain (ch^2) is a unit of area equal to the area of a square with sides measuring one chain (66 feet) each, equivalent to 4356 square feet.
History/Origin
The square chain originated in land measurement practices in England, particularly used in surveying and land division during the 19th century, especially in the context of the Imperial system.
Current Use
Today, the square chain is largely obsolete and rarely used outside historical or land survey contexts; modern measurements typically employ acres or square meters.
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.
