The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about 0.405 hectares and one hectare contains about 2.47 acres.

In 1795, when the metric system was introduced, the are was defined as 100 square metres, or one square decametre, and the hectare («hecto-» + «are») was thus 100 ares or ⁄ km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is «expected to continue indefinitely». Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially «accepted for use», they are still used in some contexts.

Description[edit]

Comparison of area units

The hectare ([2]), although not a unit of SI, is the only named unit of area that is accepted for use with SI units.[3] The name was coined in French, from the Latin ārea.[4] In practice the hectare is fully derived from the SI, being equivalent to a square hectometre. It is widely used throughout the world for the measurement of large areas of land,[5] 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[6] and Australia (since 1970).[7][8] However, the United Kingdom,[9] United States, Burma,[10][11] and to some extent Canada use the acre instead.[citation needed]

Some countries that underwent a general conversion from traditional measurements to metric measurements (e.g. Canada) required a resurvey when units of measure in legal descriptions relating to land were converted to metric units.[citation needed] Others, such as South Africa, published conversion factors which were to be used particularly «when preparing consolidation diagrams by compilation».[12]

In many countries, metrification redefined or clarified existing measures in terms of metric units. The following legacy units of area have been redefined as being equal to one hectare:[13]

• Jerib (Persian: جریب) in Iran
• Djerib (Turkish: cerip) in Turkey[14]
• Gongqing (traditional Chinese: 公頃; simplified Chinese: 公顷; pinyin: gōngqǐng) in China
• Manzana in Argentina
• Bunder in the Netherlands (until 1937)[15][16]

History[edit]

The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. The law of 18 Germinal, Year III (7 April 1795) defined five units of measure:[17]

• The metre for length
• The are (100 m2) for area [of land]
• The stère (1 m3) for volume of stacked firewood[18]
• The litre (1 dm3) for volumes of liquid
• The gram for mass

In 1960, when the metric system was updated as the International System of Units (SI), the are did not receive international recognition. The International Committee for Weights and Measures () 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».[19]

In 1972, the European Economic Community (EEC) passed directive 71/354/EEC,[20] which catalogued the units of measure that might be used within the Community. 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.

Unit family[edit]

Definition of a hectare and of an are

The names centiare, deciare, decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are.

Decimilliare[edit]

The decimilliare (sometimes seen in cadastre area evaluation of real estate plots) is ⁄ are or one square decimetre.[21]

Centiare[edit]

The centiare is one square metre.[22][23]

Deciare[edit]

The deciare (rarely used) is ten square metres.[24]

Are[edit]

The are ([25] or [26]) is a unit of area, equal to 100 square metres (10 m × 10 m), used for measuring land area. It was defined by older forms of the metric system, but is now outside the modern International System of Units (SI).[27] It is still commonly used in speech to measure real estate, in particular in Indonesia, India, and in various European countries.

In Russian and some other languages of the former Soviet Union, the are is called sotka (Russian: сотка: ‘a hundred’, i.e. 100 m2 or ⁄ hectare). 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. Many Russian dachas are 6 ares in size (in Russian, шесть соток).

Decare[edit]

The decare or dekare () is derived from deca and are, and is equal to 10 ares or 1000 square metres. It is used in Norway[28] and in the former Ottoman areas of the Middle East and Bulgaria[29] as a measure of land area. Instead of the name «decare», the names of traditional land measures are usually used, redefined as one decare:

• Stremma in Greece[30]
• Dunam, dunum, donum, or dönüm in the Balkans, Israel, Palestine, Jordan, Lebanon, Syria and Turkey[31]
• Mål is used for decare in Norway, from the old measure of about the same area.

Conversions[edit]

Metric and imperial/U.S. customary comparisons

The most commonly used units are in bold.

One hectare is also equivalent to:

• 1 square hectometre
• 15 mǔ or 0.15 qǐng[33]
• 10 dunam or dönüm (Middle East)[34]
• 10 stremmata (Greece)
• 6.25 rai (Thailand)[35]
• approximately 1.008 chō (Japan)
• approximately 2.381 feddan (Egypt)

Сколько стоит 1 гектар земли в 2022 году?

Стоимость 1 гектара земли может значительно различаться в зависимости от местоположения, типа земельного участка (сельскохозяйственный, лесной, коммерческий и т.д.), качества почвы, наличия коммуникаций, наличия построек и других факторов.

Например, в России стоимость 1 гектара сельскохозяйственной земли может колебаться от нескольких тысяч до нескольких десятков тысяч рублей, в зависимости от местоположения и качества почвы. В городах и их пригородах стоимость 1 гектара земли может быть значительно выше и достигать нескольких миллионов рублей.

В других странах стоимость земли также может значительно отличаться. Например, в США стоимость 1 гектара сельскохозяйственной земли может колебаться от нескольких тысяч до нескольких десятков тысяч долларов, в зависимости от местоположения и качества почвы.

Таким образом, точной стоимости 1 гектара земли в мире нет, так как это зависит от множества факторов, и может значительно различаться в разных регионах и странах.
