One hectare is equal to 10,000 square meters and is equivalent to approximately 2.471 acres. It is primarily used to measure land area. Hectareĭefinition: A hectare (symbol: ha) is a unit of area that is accepted in the International System of Units (SI). However, area measurements are typically not accurate enough for the difference between the two acre measurements to be detectable. The United States (US) uses both international as well as US survey acres (~4047 square meters), which vary based on which type of yard is used in the measurement. The most commonly used acre today, the international acre, is based on the international yard, which was defined in 1959.Ĭurrent use: Acres are used in countries including the United States, the UK, Ghana, India, Canada, and others. Before the metric system was adopted, many countries used their own versions of the acre. History/origin: In the Middle Ages, the acre was defined as the area that a yoke (pair) of oxen could typically plow within one day, using a wooden plow. It is defined as the area of 1 chain (66 feet) by 1 furlong (660 feet), which is exactly equal to 1/640 of a square mile, 43,560 square feet, or exactly 4046.8564224 square meters. Since bigha denotes different measurements in different states, the bigha-acre conversion would show varying values, depending on the state where the land is situated.Definition: An acre (symbol: ac) is a unit of land area used in the imperial and US customary systems. However, bigha is a unit more locally used in the northern parts of the country. In India, residential plots are measured in square feet while agricultural land is measured in acres or hectare. While an acre of land in Scotland is equivalent to 1.27 standard acres, the Irish acre is equal to 1.6 British or US acres. Note here that there is no standard measurement of an acre, and it does not denote the same area in countries where it is used. 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. 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. However, it is the UK where the unit is more commonly used. While the acre usually goes by the full name, the abbreviation “ac” is also for sometimes as the symbol of this unit.Īcre 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. Now defined in metric terms, these units also are part of the US Customary System, which derived from the British Imperial System.ĭerived from the ancient English word, aker which denotes 'open field', acre as a unit of measure has no prescribed shape. Note here that imperial units are systems of weights and measures used officially in the Great Britain from 1824 until the adoption of the metric system beginning in 1965. An acre could also be defined as an area one furlong long by 4 rods wide. 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. Most traditionally used throughout the British Empire, the Anglo-Saxon acre was defined as a strip of land 1 × 1/10 furlong, or 40 × 4 rods (660 × 66 feet). An acre is among the oldest units applied across the world to measure vast tracts of land, and has undergone a lot of changes along the way.
