Acre / Canton 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".
Canton
A canton is a type of administrative division of a country. In general, cantons are relatively small in terms of area and population when compared with other administrative divisions such as counties, departments, or provinces. Internationally, the most politically important cantons are the Swiss cantons. As the constituents of the Swiss Confederation, theoretically and historically, they are semi-sovereign states.
