Square Kilometer
A square kilometer is a unit of area equal to the area of a square with sides measuring one kilometer each.
History/Origin
The square kilometer has been used as a standard unit of area measurement in the metric system since its adoption, primarily for measuring large land areas such as countries and regions.
Current Use
It is commonly used in geography, urban planning, and environmental studies to quantify land and area sizes, especially in contexts requiring large-scale measurements.
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.
