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.
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
The acre (US survey) is still used in the United States for real estate, agriculture, and land planning, especially in rural and agricultural contexts, although the metric system is increasingly adopted globally.
