Acre / Are 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".
Are
Are, unit of area in the metric system, equal to 100 square meters and the equivalent of 0.0247 acre. Its multiple, the hectare (equal to 100 ares), is the primary unit of land measurement for most of the world. The are was the basic unit of area when the metric system was first decreed in France in 1795. When the International System of Units (SI) was adopted in 1960, the square meter replaced the are as the unit of area, but the International Bureau of Weights and Measures accepted the hectare as the common unit that can be used with the SI.
