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 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.
