Square Dekameter
A square dekameter (dam²) is a unit of area equal to the area of a square with sides measuring one dekameter (10 meters).
History/Origin
The square dekameter originated from the metric system, which was developed in the late 18th century to standardize measurements. It is derived from the dekameter, a metric unit of length, and used primarily in contexts requiring larger area measurements.
Current Use
The square dekameter is rarely used in modern practice, having been largely replaced by the hectare (ha) for land measurement. It may still be encountered in scientific or educational contexts involving metric area conversions.
Barn
A barn is a unit of area used primarily in agriculture to measure land, especially for farming purposes.
History/Origin
The barn originated as a unit of measure in the 19th century, based on the amount of land that could be covered by a barn, roughly equivalent to 40 square rods or about 40 acres, and was used in land surveying and farming contexts.
Current Use
Today, the barn is largely obsolete as a formal measurement unit but is still used colloquially in agriculture to refer to land area, especially in the United States, often informally approximating 40 acres.
