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 Hectometer
A square hectometer (hm^2) is a unit of area equal to the area of a square with sides of one hectometer (100 meters).
History/Origin
The square hectometer originated from the metric system's adoption, where 'hecto' denotes a factor of 100. It has been used primarily in scientific and geographical contexts to measure large areas.
Current Use
The square hectometer is rarely used in everyday measurements but is occasionally employed in scientific, environmental, and geographical studies to express large land or area measurements.
