The dirham, dirhem or drahm is a unit of currency and of mass. It is the name of the currencies of Moroccan dirham, Morocco, the United Arab Emirates dirham, United Arab Emirates and Armenian dram, Armenia, and is the name of a currency subdivision in Jordanian dinar, Jordan, Libyan dinar, Libya, Qatari riyal, Qatar and Tajikistani somoni, Tajikistan. It was historically a silver coin. Unit of mass The dirham was a unit of mass used across North Africa, the Middle East, Persia and Ifat Sultanate, Ifat; later known as Adal Sultanate, Adal, with varying values. The value of Islamic dirham was 14 qirat. 10 dirham equals 7 mithqal (2.975 gm of silver). In the late Ottoman Empire (), the standard dirham was 3.207 gram, g; 400 dirhem equal one oka (measure), oka. The Ottoman dirham was based on the Sassanian, Sasanian drachm (in Middle Persian: 饜饜饜饜 ''drahm''), which was itself based on the Greek Ancient drachma, dram/drachma.

Silver Dirham LACMA M
Silver is a chemical element; it has symbol Ag () and atomic number 47. A soft, whitish-gray, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. Silver is found in the Earth's crust in the pure, free elemental form (" native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures. Other than in currency and as an investment medium (coins and bullion), silver is used in solar pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxford English Dictionary
The ''Oxford English Dictionary'' (''OED'') is the principal historical dictionary of the English language, published by Oxford University Press (OUP), a University of Oxford publishing house. The dictionary, which published its first edition in 1884, traces the historical development of the English language, providing a comprehensive resource to scholars and academic researchers, and provides ongoing descriptions of English language usage in its variations around the world. In 1857, work first began on the dictionary, though the first edition was not published until 1884. It began to be published in unbound Serial (literature), fascicles as work continued on the project, under the name of ''A New English Dictionary on Historical Principles; Founded Mainly on the Materials Collected by The Philological Society''. In 1895, the title ''The Oxford English Dictionary'' was first used unofficially on the covers of the series, and in 1928 the full dictionary was republished in 10 b ...

Troy Grain
A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly . It is nominally based upon the mass of a single ideal seed of a cereal. From the Bronze Age into the Renaissance, the average masses of wheat and barley grains were part of the legal definitions of units of mass. Expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas. Another source states that it was defined such that 252.458 units would balance of distilled water at an ambient air-water pressure and temperature of and respectively. Another book states that Captain Henry Kater, of the British Standards Commission, arrived at this value experimentally. The grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass. The unit was based on the weight of a single grain of barley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancient Drachma
In ancient Greece, the drachma (, ; Grammatical number, pl. drachmae or drachmas) was an ancient currency unit issued by many city-states during a period of ten centuries, from the Archaic Greece, Archaic period throughout the Classical Greece, Classical period, the Hellenistic period up to the Roman period. The ancient drachma originated in Greece around the 6th century BC. The coin, usually made of silver or sometimes gold had its origins in a bartering system that referred to a drachma as a handful of wooden spits or arrows. The drachma was unique to each city state that minted them, and were sometimes circulated all over the Mediterranean. The coinage of Classical Athens, Athens was considered to be the strongest and became the most popular. Origins The name ''drachma'' is derived from the verb (, "(I) grasp"). It is believed that the same word with the meaning of "handful" or "handle" is found in Linear B tablets of the Mycenaean Greece, Mycenean Pylos. Initially a dra ...

Middle Persian
Middle Persian, also known by its endonym P膩rs墨k or P膩rs墨g ( Inscriptional Pahlavi script: , Manichaean script: , Avestan script: ) in its later form, is a Western Middle Iranian language which became the literary language of the Sasanian Empire. For some time after the Sasanian collapse, Middle Persian continued to function as a prestige language. It descended from Old Persian, the language of the Achaemenid Empire and is the linguistic ancestor of Modern Persian, the official language of Iran (also known as Persia), Afghanistan ( Dari) and Tajikistan ( Tajik). Name "Middle Iranian" is the name given to the middle stage of development of the numerous Iranian languages and dialects. The middle stage of the Iranian languages begins around 450 BCE and ends around 650 CE. One of those Middle Iranian languages is Middle Persian, i.e. the middle stage of the language of the Persians, an Iranian people of Persia proper, which lies in the south-western Iran highlands on ...

Sassanian
The Sasanian Empire (), officially Eranshahr ( , "Empire of the Iranian peoples, Iranians"), was an List of monarchs of Iran, Iranian empire that was founded and ruled by the House of Sasan from 224 to 651. Enduring for over four centuries, the length of the Sasanian dynasty's reign over ancient Iran was second only to the directly preceding Arsacid dynasty of Parthia. Founded by Ardashir I, whose rise coincided with the decline of Arsacid influence in the face of both internal and external strife, the House of Sasan was highly determined to restore the legacy of the Achaemenid Empire by expanding and consolidating the Iranian nation's dominions. Most notably, after defeating Artabanus IV of Parthia during the Battle of Hormozdgan in 224, it began competing far more zealously with the neighbouring Roman Empire than the Arsacids had, thus sparking a new phase of the Roman鈥揑ranian Wars. This effort by Ardashir's dynasty ultimately re-established Iran as a major power of late an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oka (measure)
The oka, okka, or oke () was an Ottoman Empire, Ottoman measure of mass, equal to 400 dirham, dirhems (Ottoman dram (unit), drams). Its value varied, but it was standardized in the late empire as 1.2829 kilograms. 'Oka' is the most usual spelling today; 'oke' was the usual contemporary English spelling; 'okka' is the modern Turkish spelling, and is usually used in academic work about the Ottoman Empire. In Albania, oka varied in weight between 1.25 kg (small oka) and 1.408 kg (large oka) depending on the region. It was formally replaced by the metric system in 1922 but continued to be used until a comprehensive implementation of the metric system in 1946. In Turkey, the traditional unit is now called the ''eski okka'' 'old oka' or ''kara okka'' 'black okka'; the ''yeni okka'' 'new okka' is the kilogram. In Greece, the oka (, plural ) was standardized at 1.282 kilogram, kg and remained in use until traditional units were abolished on March 31, 1953鈥攖he SI, metric system had been a ...

Kilogram
The kilogram (also spelled kilogramme) is the base unit of mass in the International System of Units (SI), equal to one thousand grams. It has the unit symbol kg. The word "kilogram" is formed from the combination of the metric prefix kilo- (meaning one thousand) and gram; it is colloquially shortened to "kilo" (plural "kilos"). The kilogram is an SI base unit, defined ultimately in terms of three defining constants of the SI, namely a specific transition frequency of the caesium-133 atom, the speed of light, and the Planck constant. A properly equipped metrology laboratory can calibrate a mass measurement instrument such as a Kibble balance as a primary standard for the kilogram mass. The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water (originally at 0 掳C, later changed to the temperature of its maximum density, approximately 4 掳C). The current definition of a kilogram agrees with this original defini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gram
The gram (originally gramme; SI unit symbol g) is a Physical unit, unit of mass in the International System of Units (SI) equal to one thousandth of a kilogram. Originally defined in 1795 as "the absolute Mass versus weight, weight of a volume of pure water equal to Cube (algebra), the cube of the hundredth part of a metre [1 Cubic centimetre, cm3], and at Melting point of water, the temperature of Melting point, melting ice", the defining temperature (0 掳C) was later changed to the temperature of maximum density of water (approximately 4 掳C). Subsequent redefinitions agree with this original definition to within 30 Parts-per notation, parts per million (0.003%), with the maximum density of water remaining very close to 1 g/cm3, as shown by modern measurements. By the late 19th century, there was an effort to make the Base unit (measurement), base unit the kilogram and the gram a derived unit. In 1960, the new International System of Units defined a '' ...
