An acre is an English Unit of area, which is also frequently used in the United States, the United Kingdom and some Commonwealth countries. It is most often used to describe areas of land. UK DEFINITION The acre in the UK is 43,560 square feet or 4,840 square yards. The The Units of Measurement Regulations 1995 express the conversion factor of 4,046.8564224 M&2 , based on the definition of the yard in the Weights and Measures Act of 1963. U.S. CUSTOMARY UNITS The . However, the U.S. has two slightly different definitions of foot (''international'' and ''survey'') and thus two definitions of acre:
Although these being used interchangably in most contexts due to the popular unawareness of a special survey definition, the survey acre is actually the standard one. RELATED MEASUREMENTS Two related linear measurements are the acre's length and the '''acre's breadth'''.
CONVERSION An international acre may be Converted to other units because it is equivalent to exactly:
An acre is equivalent to approximately:
One Square Mile is 640 acres. A square parcel of land ¼ mile wide is 40 acres. A square parcel of land ½ mile on a side (i.e. a quarter-section) is 160 acres, the usual land tract under the Homestead Act in the United States . This results in common field lengths of ½ mile, with every Rod in width equal to one acre. One acre is slightly less than 91 yards on an American Football field, with the full field, including the end zones, covering approximately 1.32 acres. HISTORY The acre was selected as approximately the amount of land tillable by one man behind an long''. Statutory values for the acre were enacted in England by acts of:
In the UK the use of acres is now officially discouraged, but it remains a very familiar measure of land with the general public, especially among middle-aged and elderly people. An acre is a measure of "flat" area, not actual area. To understand this, visualize a rectangle one furlong long by one chain wide drawn on a map. The area enclosed by this rectangle is defined to be an acre—and on perfectly level ground the actual area ''will be'' one acre. On sloping ground, however, the actual area of the terrain, as calculated mathematically, will be greater than an acre. Spanish Landgrant System In the archaic system of old Spanish land grants affecting Texas and parts of adjoining states, two other measures of land are used, the ''(square) league'' and the ''labor''. (Labor is pronounced "Luh-BOR" in West Texas). The league is equivalent to 4,428 acres and the Labor to 177 acres. The labor is often used as an approximate equivalent to a ''quarter-section'', i.e. one-quarter of a square mile, of land. These measures are still encountered in modern real estate transcations.
