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).

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.
Acre (Us Survey)
An acre (US survey) is a unit of area used primarily in land measurement, equal to 43,560 square feet or approximately 4,046.86 square meters.
History/Origin
The acre originated in medieval England as a measure of land area that could be plowed in one day with a yoke of oxen. It was standardized in the United States based on the survey system, maintaining its traditional size for land measurement purposes.
Current Use
