Acre / Dm2 Units Definition
Acre
The acre (/ˈeɪkər/ AY-kər) is a unit of land area used in the British imperial and the United States customary systems. It is traditionally defined as the area of one chain by one furlong (66 by 660 feet), which is exactly equal to 10 square chains, 1⁄640 of a square mile, 4,840 square yards, or 43,560 square feet, and approximately 4,047 m2, or about 40% of a hectare. Based upon the international yard and pound agreement of 1959, an acre may be declared as exactly 4,046.8564224 square metres. The acre is sometimes abbreviated ac but is usually spelled out as the word "acre".
dm2 (Square decimeter)
Therefore, a square decimeter (or "square decimeter" in British spelling) is one tenth of a square meter. It can also be expressed by ten square centimeters. A rough example of a decimeter could be the average surface area of some smartphone screens.
