The hectare ( / ˈ h ɛ k t ɛər , - t ɑːr / ; SI symbol: ha ) is a non-SI metric unit of area equal to a square with 100- metre sides (1 hm ), that is, 10,000 square metres (10,000 m ), 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.
23-585: The Leasowes / ˈ l ɛ z ə z / is a 57- hectare (around 141 acre ) estate in Halesowen , historically in the county of Shropshire , later (from 1844) Worcestershire , England , comprising house and gardens. The parkland is now listed Grade I on English Heritage 's Register of Parks and Gardens and the home of the Halesowen Golf Club. The name means "rough pasture land". Developed between 1743 and 1763 by poet William Shenstone as
46-519: A ferme ornée , the garden is one of the most admired early examples of the English garden . Its importance lies in its simplicity and the uncompromisingly rural appearance. Thomas Whately praises it in chapter LII of his Observations on Modern Gardening of 1770: The ideas of pastoral poetry seem now to be the standard of that simplicity; and a place conformable to them is deemed a farm in its utmost purity. An allusion to them evidently enters into
69-679: A dash ; for example, 1-21-00.26 ha would mean 1 hectare, 21 ares, and 0.26 centiares (12,100.26 m ). 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: 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 ( CIPM ) makes no mention of
92-404: A double prefix is non-standard. The decimilliare is (100 mm) or roughly a four-inch-by-four-inch square. The centiare is one square metre. The deciare (rarely used) is ten square metres. The are ( / ɑːr / or / ɛər / ) 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

138-439: A few other units including the are (and implicitly the hectare ) whose use was limited to the measurement of land. 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 decimilliare (dma, sometimes seen in cadastre area evaluation of real estate plots) is 1 ⁄ 10,000 are or one square decimetre. Such usage of

With Whately's treatise guiding him every step of the way, in April 1786, polymath Thomas Jefferson , the future third President of the United States , visited the Leasowes (then owned by Edward Horne) on his tour of English gardens in the company of his close friend and future second President of

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 m or 1 ⁄ 100 hectare). It is used to describe

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 units that were catalogued replicated the recommendations of the CGPM, supplemented by

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 , New Zealand and Australia (since 1970). However,

Wotton is both great and elegant, though neglected ... Shenstone's Leasowes is the simplest and plainest, but the most rural of all. I saw no spot so small that exhibited such a variety of beauties. Jefferson's more purposeful and inquisitive account in his Notes of
322-947: The United Kingdom, the United States, Myanmar (Burma), and to some extent Canada, use the acre instead of the hectare for measuring surface or land area. 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. Others, such as South Africa, published conversion factors which were to be used particularly "when preparing consolidation diagrams by compilation". 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: In Mexico, land area measurements are commonly given as combinations of hectares, ares, and centiares. These are commonly written separated by
345-458: The age of 45. In June 1795, Edward Butler Hartopp became the owner of the estate, and held possession till July 1800, when it was transferred to Charles Hamilton, and when he became insolvent in 1807, it passed into the hands of Matthias Attwood, who unlike the previous owners did not take any action to preserve William Shenstone's park features, and by the 1820s the park grounds had sunk into a "state of ruin and desolation".

391-514: The dekare/decare daa (1,000 m ) and are (100 m ) are not officially "accepted for use", they are still used in some contexts. 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 . The name was coined in French, from the Latin ārea . In practice the hectare is fully derived from
414-527: The design of the Leasowes, where they appear so lovely as to endear the memory of their author; and justify the reputation of Mr. Shenstone … every part is rural and natural. It is literally a grazing farm lying round the house; and a walk as unaffected and as unadorned as a common field path, is conducted through the several enclosures. [After this passage, Whately goes on to describe every detail]. Shenstone died in 1763. The house and grounds were purchased by Edward Horne, who demolished Shenstone's house and built
437-478: The hectare (" hecto- " + "are") was thus 100 ares or 1 ⁄ 100 km (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units ( SI ), 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
460-440: The inscriptions are lost. In 1789 Edward Horne sold the property to Major Francis Halliday who made considerable additions to the house and parkland. He added a stone portico at the entrance of the house and a folly hermitage in the high wood, which was decorated with "stained glass windows, furnace cinders, cowheel bones, horses' teeth, etc." (this was not in keeping with Shenstone's park improvements). Halliday died in 1794, at

Between 1897 and 1907, it housed the Anstey College of Physical Education . Part of

Halesowen Council (later to become Dudley Metropolitan Borough Council ) purchased The Leasowes in 1934 and since then the site has been managed as a public park with part of the site leased to Halesowen Golf Club. Neglected since Shenstone's death, restoration of the 18th century landscape began in May 2008 and was completed by January 2009 (several months ahead of schedule). The restoration included

It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as
