Square Rod (Us Survey)
A square rod (US survey) is a unit of area equal to the area of a square with sides measuring one rod (16.5 feet) each, used primarily in land measurement.
History/Origin
The square rod originated from the traditional land measurement system in the United States, particularly in surveying and real estate, where the rod was a common unit of length. It has been used historically for measuring plots of land, especially in rural and agricultural contexts.
Current Use
Today, the square rod (US survey) is largely obsolete and replaced by more modern units like acres. However, it may still be encountered in historical land records and surveying documents.
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.
