Acre
Definition: An acre is a unit of land area used in imperial and US customary systems. Traditionally defined as the area of one chain (66 feet) by one furlong (660 feet), which equals exactly 43,560 square feet or about 4,047 square meters (0.4047 hectares).
History: Dating back to medieval England, the acre represented the amount of land a yoke of oxen could plow in one day. It was standardized to its current definition in the British Imperial system and later adopted by the US.
