An acre is the name of a Unit of Area in a number of different systems, including Imperial Unit s and United States Customary Units . The most commonly used acres today are the international acre and, in the United States , the survey acre. One acre comprises 4,840 Square Yard s or 43,560 Square Feet . Because of alternative definitions of a yard or a foot, the exact size of an acre also varies slightly. Traditionally, an acre was a swath of land one Furlong long and one Chain wide. A modern acre can have arbitrary dimensions as long as the area is correct. For example, a strip of land 1 Inch wide and 99 Mile s long is also an acre. The acre is often used to express areas of land. In the Metric System , the Hectare is commonly used for the same purpose. An acre is approximately 0.4 hectare.

The acre was selected as approximately the amount of land tillable by one man behind an Ox in one Day . This explains one definition as the area of a rectangle with sides of length one Chain and one Furlong . A long narrow strip of land is more efficient to plough than a square plot, since the plough does not have to be turned so often. The word "furlong" itself derives from the fact that it is ''one Furrow long''. Statutory values for the acre were enacted in England by acts of:
Historically the size of farms and landed estates in the United Kingdom was always expressed in acres, even if the number of acres was so large that it might conveniently have been expressed in square miles. For example a certain landowner might have been said to own 32,000 acres of land, not 50 square miles of land. OTHER ACRES
