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.
Square Decimeter
A square decimeter (dm^2) is a unit of area equal to the area of a square with sides of one decimeter (10 centimeters).
History/Origin
The square decimeter is derived from the decimeter, a metric unit of length, and has been used in metric measurements for expressing small to moderate areas, especially in scientific and engineering contexts since the adoption of the metric system.
Current Use
The square decimeter is used in various fields such as engineering, architecture, and science for measuring small surface areas, particularly where metric units are standard and precise measurements are required.
