Used in the imperial system of units and the US system, the modern acre is equal to 4,840 square yards, 43,560 square feet, 4,047 square metres and 0.4047 hectares.

History of Acre
Mentioned from the ancient English word, aker which means ‘open field’, acre as a unit of measure has no defined shape. While the acre usually goes by the full name, the abbreviation “ac” is also for sometimes as the symbol of this unit.
Acre is widely used all across the world as a land measurement unit, including Canada, Jamaica, the US, Spain, France, Germany and most of South Asia, including India, Pakistan, Sri Lanka and Bangladesh. However, it is the UK where the unit is more commonly used. In the middle age in England, an acre of land was defined as an area that could be ploughed in one day by a yoke of oxen. Such has been the popularity of this measurement unit across the British Empire that the size of farms usually expressed in acres even if expressing them in square miles made better sense because of the large numbers involved.
