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.
20-476: The Melbourne General Cemetery is a large (43 hectare ) necropolis located 3 km (1.9 mi) north of the city of Melbourne in the suburb of Carlton North . The cemetery is notably the resting place of five Prime Ministers of Australia , more than any other necropolis within Australia. Former Prime Minister Harold Holt 's headstone is a memorial, as his remains have never been discovered. The cemetery
40-661: 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
60-404: 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
80-439: 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
100-542: A measure of land area. The names of the older land measures of similar size are usually used, redefined as exactly one decare: The most commonly used units are in bold . One hectare is also equivalent to: The Unicode character U+33CA ㏊ SQUARE HA , in the CJK Compatibility block, is intended for compatibility with pre-existing East Asian character codes. It is not intended for use in alphabetic contexts. U+3336 ㌶ SQUARE HEKUTAARU
120-463: 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 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
140-670: Is a combination of ヘクタール ( hekutāru ), the Japanese translation of "hectare". Square metre The square metre ( international spelling as used by the International Bureau of Weights and Measures ) or square meter ( American spelling ) is the unit of area in the International System of Units (SI) with symbol m . It is the area of a square with sides one metre in length. Adding and subtracting SI prefixes creates multiples and submultiples; however, as
160-431: Is interred at Melbourne General Cemetery, William Champ . There are two Governors of Victoria , Sir Charles Hotham and Sir James Gobbo , and one Governor-General of Australia , Sir Isaac Isaacs , buried at Melbourne General Cemetery. The cemetery contains the war graves of 91 Commonwealth service personnel, more than 30 from World War I and more than 50 from World War II . A monument in memory of Elvis Presley
180-451: Is now outside the modern International System of Units (SI). 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
200-1130: The European Union , New Zealand and Australia (since 1970). However, 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
220-573: The are in the 2019 edition of the SI brochure, but classifies the hectare as a "Non-SI unit accepted for use with the International System of Units". 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

#1732845389728240-455: The cemetery's 'Prime Ministers Garden': Sir Robert Menzies (including Dame Pattie Menzies ), Sir John Gorton , Malcolm Fraser and Bob Hawke (half of Hawkes ashes are at Melbourne, the other half are interred in Sydney ). Harold Holt 's (including his wife Dame Zara Bate ) is a memorial, as his body was never recovered after he disappeared at sea . Dame Zara is buried at Sorrento Cemetery,
260-683: The closest burial ground to where Holt disappeared. James Scullin (including Sarah Scullin ) is buried in the Catholic section of the cemetery. There are eight Premiers of Victoria buried in the Melbourne General Cemetery, more than any other necropolis around the state. Premiers George Elmslie , James Francis , Duncan Gillies , Richard Heales , William Nicholson , Sir John O'Shanassy , Sir James Patterson , and James Service . Sir Robert Menzies served as Deputy Premier of Victoria between 1932 and 1934. The first Premier of Tasmania
280-416: 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 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
300-447: The monument but these were cancelled because of the undue media attention they attracted. One particular incident saw local TV camera crews causing a traffic jam that held up a funeral procession for a recently-deceased person. The decision was then made to simply allow fans to visit in their own time. The monument is regularly visited by Presley fans to this day, especially on the anniversary of his death. Hectare In 1795, when
320-580: 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 ). 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. It is used in Norway and in the former Ottoman areas of the Middle East and Bulgaria as
340-399: The unit is exponentiated , the quantities grow exponentially by the corresponding power of 10 . For example, 1 kilometre is 10 (one thousand ) times the length of 1 metre, but 1 square kilometre is (10 ) (10 , one million ) times the area of 1 square metre, and 1 cubic kilometre is (10 ) (10 , one billion ) cubic metres. The square metre may be used with all SI prefixes used with
360-516: Was coined in French, from the Latin ārea . 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, 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
380-564: Was erected in the cemetery by the Elvis Presley Fan Club of Victoria on 26 November 1977, three months after the singer's passing on 16 August of that year. The monument was personally approved by Vernon Presley and was erected even before the equivalent monument in Presley's hometown of Memphis, Tennessee . It was unveiled by Johnny O'Keefe , just under a year before his own passing on 6 October 1978. Fan club vigils were initially held at
400-576: Was established in 1852 and opened on 1 June 1853, and the Old Melbourne Cemetery (on the site of what is now the Queen Victoria Market ) was closed the next year. The grounds feature several heritage buildings, many in bluestone, including a couple of chapels and a number of cast iron pavilions. The gatehouses are particularly notable. Six Prime Ministers of Australia are memorialised at Melbourne General Cemetery. Four are interred in
