Stremma
The stremma ( stremmata; el, στρέμμα, ''strémma'') is a Greek unit of land area equal to 1,000 square metres. Historically, stremmata were not standardized, and may have been anywhere from . History The Ancient Greece, ancient Greek Greek units, equivalent was the square plethron, which served as the Greeks' form of the acre (unit), acre. It was originally defined as the distance plowed by a team of oxen in a day but was nominally standardized as the area enclosed by a square 100 Greek feet (''pous'') to a side. It was the size of a Greek wrestling square. The Byzantine units, Byzantine or Morean stremma continued to vary depending on the period and the quality of the land, but usually enclosed an area between . It was originally also known as the "plethron" but this was eventually replaced by "stremma", derived from the verb for "turning" the ground with a Byzantine plow. The Ottoman units of measurement, Ottoman stremma, often called the Turkish units of measuremen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunam
A dunam ( Ottoman Turkish, Arabic: ; tr, dönüm; he, דונם), also known as a donum or dunum and as the old, Turkish, or Ottoman stremma, was the Ottoman unit of area equivalent to the Greek stremma or English acre, representing the amount of land that could be ploughed by a team of oxen in a day. The legal definition was "forty standard paces in length and breadth", but its actual area varied considerably from place to place, from a little more than in Ottoman Palestine to around in Iraq.Λεξικό της κοινής Νεοελληνικής (Dictionary of Modern Greek), Ινστιτούτο Νεοελληνικών Σπουδών, Θεσσαλονίκη, 1998. The unit is still in use in many areas previously ruled by the Ottomans, although the new or metric dunam has been redefined as exactly one decare (), which is 1/10 hectare (1/10 × ), like the modern Greek royal stremma. History The name dönüm, from the Ottoman Turkish ''dönmek'' (, "to turn"), appears ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metric Units
Metric units are units based on the metre, gram or second and decimal (power of ten) multiples or sub-multiples of these. The most widely used examples are the units of the International System of Units (SI). By extension they include units of electromagnetism from the CGS and SI units systems, and other units for which use of SI prefixes has become the norm. Other unit systems using metric units include: * International System of Electrical and Magnetic Units * Metre–tonne–second (MTS) system of units * MKS system of units (metre, kilogram, second) Metric units that are part of the SI The first group of metric units are those that are at present defined as units within the International System of Units (SI). In its most restrictive interpretation, this is what may be meant when the term ''metric unit'' is used. The SI defines 30 named units and associated symbols: * The unit one (1) is the unit of a quantity of dimension one. * The second (s) is the unit of time. * The ...

Square Plethron
Plethron ( grc-gre, , plural ''plethra'') is an ancient unit of Greek measurement equal to 97 to 100 Greek feet (ποῦς, ''pous''; c. 30 meters), although the measures for plethra may have varied from polis to polis. This was roughly the width of a typical ancient Greek athletic running-track. A plethron could also be used as a unit of measured area, and reference to the unit in defining the size of a wrestling area is made by Libanius.Libanius, '' Orationes'', Chapter 10. A square plethron of c. 30 by 30 meters was used as the standard dimensions of a Greek wrestling square, since such competitions were held within the racing track in ancient Greece. In other connotations, it functioned as the Greek acre, and varied in size to accommodate the amount of land a team of oxen could plow in a day. The plethron continued to be used in the Byzantine Empire, where its variant uses were ultimately codified to refer to an area defined by sides of 100 feet or 40 paces (βῆμα, bema ...

Greek Wrestling
Greek wrestling ( grc-gre, πάλη, pálē), also known as Ancient Greek wrestling and Palé, was the most popular organized sport in Ancient Greece. A point was scored when one player touched the ground with his back, hip or shoulder, or conceding defeat due to a submission-hold or was forced out of the wrestling-area. Three points had to be scored to win the match. One particularly important position in this form of wrestling was one where one of the contestants was lying on his abdomen with the other on his back trying to strangle him (back mount). The athlete on the bottom would try to grasp an arm of the one on top and turn him over onto his back while the athlete on top would try to complete the choke without being rolled. Wrestling was the first competition to be added to the Olympic Games that was not a footrace. It was added in 708 B.C. (Miller, 46). The competitions were held in elimination-tournament style until one wrestler was crowned the victor. The wrestling area ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hectare
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 and one hectare contains about . 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 The hectare (), although not a unit of SI, i ...

Conversion Of Units
Conversion of units is the conversion between different units of measurement for the same quantity, typically through multiplicative conversion factors which change the measured quantity value without changing its effects. Overview The process of conversion depends on the specific situation and the intended purpose. This may be governed by regulation, contract, technical specifications or other published standards. Engineering judgment may include such factors as: * The precision and accuracy of measurement and the associated uncertainty of measurement. * The statistical confidence interval or tolerance interval of the initial measurement. * The number of significant figures of the measurement. * The intended use of the measurement including the engineering tolerances. * Historical definitions of the units and their derivatives used in old measurements; e.g., international foot vs. US survey foot. Some conversions from one system of units to another need to be exact, without ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Square Foot
The square foot (plural square feet; abbreviated sq. ft, sf, or ft2; also denoted by '2) is an imperial unit and U.S. customary unit (non- SI, non-metric) of area, used mainly in the United States and partially in Canada, the United Kingdom, Bangladesh, India, Nepal, Pakistan, Ghana, Liberia, Malaysia, Myanmar, Singapore and Hong Kong. It is defined as the area of a square with sides of 1 foot. Although the pluralization is regular in the noun form, when used as an adjective, the singular is preferred. So, an apartment measuring 700 square feet could be described as a 700 square-foot apartment. This corresponds to common linguistic usage of ''foot.'' The square foot unit is commonly used in real estate. Dimensions are generally taken with a laser device, the latest in a long line of tools used to gauge the size of apartments or other spaces. Real estate agents often measure straight corner-to-corner, then deduct non-heated spaces, and add heated spaces whose footprints exceed th ...
