Acre / Hectare 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".
Hectare
hectare, unit of area in the metric system equal to 100 ares, or 10,000 square meters, and the equivalent of 2.471 acres in the British imperial system and the customary measurement of the United States. The term is derived from the Latin area and hect, an irregular contraction of the Greek word percent. Although the are is the primary metric unit of land measurement, the hectare is more commonly used in practice. The hectare is, by definition, equal to one djerib in Turkey, one jerib in Iran, one gong qing in mainland China, one manzana in Argentina and one bunder in the Netherlands.
