Current Use
The acre (US survey) is still used in the United States for real estate, agriculture, and land planning, especially in rural and agricultural contexts, although the metric system is increasingly adopted globally.
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.
