Instead of the name "decare", the names of traditional land measures are usually used, redefined as one decare: It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as a measure of land area. The decare or dekare ( / ˈ d ɛ k ɑːr, - ɛər/) is derived from deca and are, and is equal to 10 ares or 1000 square metres. Many Russian dachas are 6 ares in size (in Russian, шесть соток). It is used to describe the size of suburban dacha or allotment garden plots or small city parks where the hectare would be too large. In Russian and some other languages of the former Soviet Union, the are is called sotka (Russian: сотка: 'a hundred', i.e. It is still commonly used in speech to measure real estate, in particular in Indonesia, India, and in various European countries. It was defined by older forms of the metric system, but is now outside the modern International System of Units (SI). The are ( / ɑːr/ or / ɛər/ ) is a unit of area, equal to 100 square metres ( 10 m × 10 m), used for measuring land area.
The deciare (rarely used) is ten square metres. The decimilliare (dma, sometimes seen in cadastre area evaluation of real estate plots) is 1⁄ 10,000 are or one square decimetre. The names centiare, deciare, decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are. The units that were catalogued replicated the recommendations of the CGPM, supplemented by a few other units including the are (and implicitly the hectare) whose use was limited to the measurement of land. In 1972, the European Economic Community (EEC) passed directive 71/354/EEC, which catalogued the units of measure that might be used within the Community. The International Committee for Weights and Measures ( CIPM) makes no mention of the are in the current (2006) definition of the SI, but classifies the hectare as a "Non-SI unit accepted for use with the International System of Units". In 1960, when the metric system was updated as the International System of Units (SI), the are did not receive international recognition. The litre (1 dm 3) for volumes of liquid.The stère (1 m 3) for volume of stacked firewood.The law of 18 Germinal, Year III (7 April 1795) defined five units of measure: The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. Bunder in the Netherlands (until 1937).Gongqing ( traditional Chinese: 公頃 simplified Chinese: 公顷 pinyin: gōngqǐng) in China.
The following legacy units of area have been redefined as being equal to one hectare: In many countries, metrification redefined or clarified existing measures in terms of metric units. Others, such as South Africa, published conversion factors which were to be used particularly "when preparing consolidation diagrams by compilation". Canada) required a resurvey when units of measure in legal descriptions relating to land were converted to metric units. Some countries that underwent a general conversion from traditional measurements to metric measurements (e.g. However, the United Kingdom, United States, Burma, and to some extent Canada use the acre instead. It is widely used throughout the world for the measurement of large areas of land, and it is the legal unit of measure in domains concerned with land ownership, planning, and management, including law ( land deeds), agriculture, forestry, and town planning throughout the European Union and In practice the hectare is fully derived from the SI, being equivalent to a square hectometre. The name was coined in French, from the Latin ārea. The hectare ( / ˈ h ɛ k t ɛər, - t ɑː r/ ), although not a unit of SI, is the only named unit of area that is accepted for use with SI units. Trafalgar Square has an area of about one hectare.
