Apothecaries' System
The apothecaries' system, or apothecaries' weights and measures, is a historical system of mass and volume units that were used by physicians and apothecaries for medical prescriptions and also sometimes by scientists."Medicinal-Gewicht, Apotheker-Gewicht ist dasjenige Gewicht, nach welchem Aerzte und Apotheker die Quantitäten der Arzneimittel bestimmen. Nur an wenigen Orten werden beide Arten der Gewichte unterschieden und Medicinalgewicht bei dem Einkauf der Arzneiwaaren im Großen von dem Apothekergewicht bei der Anfertigung und dem Einzel-Verkauf in den Apotheken getrennt. In diesem Fall ist das Medicinalgewicht dem gewöhnlichen Landesgewicht beinahe oder völlig gleich und das Pfund wird dann in 16 Unzen getheilt. Bei dem eigentlichen Apothekergewicht aber nimmt man nur einen Theil des Landesgewichts und theilt dieses Pfund in 12 Unzen oder 96 Drachmen oder 288 Scrupel oder 5760 Gran oder 7452 Aß." The English version of the system is closely related to the English troy s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mina (unit)
The mina (also mĕnē, Aramaic; ) is an ancient Near Eastern unit of weight, which was divided into 60 shekels. The mina, like the shekel, was also a unit of currency. History The word mina comes from the ancient Semitic root / 'to count', Akkadian , he, מָנָה (), arc, מָנָה, script=Hebr/ (/), syc, ܡܢܳܐ (), uga, 𐎎𐎐, mn. It is mentioned in the Bible, where Solomon is reported to have made 300 shields, each with 3 "mina" of gold ( he, מָנֶה, mane, links=no), or later after the Edict of Cyrus II of Persia the people are reported to have donated 5000 mina of silver for the reconstruction of Solomon's Temple in Jerusalem. From earliest Sumerian times, a mina was a unit of weight. At first, talents and shekels had not yet been introduced. By the time of Ur-Nammu (shortly before 2000 BCE), the mina had a value of talent as well as 60 shekels. The weight of this mina is calculated at . Writings from Ugarit give the value of a mina as equivalent to fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whisky Tasting Glass
Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of sherry are also sometimes used. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels. Etymology The word ''whisky'' (or ''whiskey'') is an anglicisation of the Classical Gaelic word (or ) meaning "water" (now written as in Modern Irish, and in Scottish Gaelic). This Gaelic word shares its ultimate origins with Germanic ''water'' and Slavic ''voda'' of the same meaning. Distilled alcohol was known in Latin as ("water of life"). This was translated into Old ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy Ounce
Troy weight is a system of units of mass that originated in 15th-century England, and is primarily used in the precious metals industry. The troy weight units are the grain, the pennyweight (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). The troy grain is equal to the grain unit of the avoirdupois system, but the troy ounce is heavier than the avoirdupois ounce, and the troy pound is lighter than the avoirdupois pound. One troy ounce (oz t) equals exactly 31.1034768 grams. Etymology Troy weight probably takes its name from the French market town of Troyes where English merchants traded at least as early as the early 9th century. The name ''troy'' is first attested in 1390, describing the weight of a platter, in an account of the travels in Europe of the Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize of Weights and Measures'' (also known as ), one of the statutes of uncertain date from the ...

Grain (mass)
A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly milligrams. 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, essentially the premodern equivalent of legal boilerplate. 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' system ...

Ounce
The ounce () is any of several different units of mass, weight or volume and is derived almost unchanged from the , an Ancient Roman unit of measurement. The avoirdupois ounce (exactly ) is avoirdupois pound; this is the United States customary and British imperial ounce. It is primarily used in the United States to measure packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere. Although the avoirdupois ounce is the mass measure used for most purposes, the 'troy ounce' of exactly is used instead for the mass of precious metals such as gold, silver, platinum, palladium, rhodium, etc. The term 'ounce' is also used in other contexts: * The ounce-force is a measure of force (see below). * The fluid ounce is a measure of volume. Historically, a variety of different ounces measuring mass or volume were used in different jurisdictions by different trades and at differe ...

Pound (mass)
The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement. Various definitions have been used; the most common today is the international avoirdupois pound, which is legally defined as exactly , and which is divided into 16 avoirdupois ounces. The international standard symbol for the avoirdupois pound is lb; an alternative symbol is lbm (for most pound definitions), # ( chiefly in the U.S.), and or ″̶ (specifically for the apothecaries' pound). The unit is descended from the Roman (hence the abbreviation "lb"). The English word ''pound'' is cognate with, among others, German , Dutch , and Swedish . These units are historic and are no longer used (replaced by the metric system). Usage of the unqualified term ''pound'' reflects the historical conflation of mass and weight. This accounts for the modern distinguishing terms ''pound-mass'' and '' pound-force''. Etymology The word 'pound' and its cognates ...

Weights And Measures Acts (UK)
Weights and measures acts are acts of the British Parliament determining the regulation of weights and measures. It also refers to similar royal and parliamentary acts of the Kingdoms of England and Scotland and the medieval Welsh states. The earliest of these were originally untitled but were given descriptive glosses or titles based upon the monarch under whose reign they were promulgated. Several omnibus modern acts are entitled the Weights and Measures Act and are distinguished by the year of their enactment. Background There have been many laws concerned with weights and measures in the United Kingdom or parts of it over the last 1,000 or so years. The acts may catalogue lawful weights and measures, prescribe the mechanism for inspection and enforcement of the use of such weights and measures and may set out circumstances under which they may be amended. Modern legislation may, in addition to specific requirements, set out circumstances under which the incumbent mini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sassanian
The Sasanian () or Sassanid Empire, officially known as the Empire of Iranians (, ) and also referred to by historians as the Neo-Persian Empire, was the last Iranian empire before the early Muslim conquests of the 7th-8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).Norman A. Stillman ''The Jews of Arab Lands'' pp 22 Jewish Publication Society, 1979 International Congress of Byzantine Studies ''Proceedings of the 21st International Congress of Byzantine Studies, London, 21–26 August 2006, Volumes 1–3'' pp 29.

Dirhem
The dirham, dirhem or dirhm ( ar, درهم) is a silver unit of currency historically and currently used by several Arab and Arab influenced states. The term has also been used as a related unit of mass. Unit of mass The dirham was a unit of weight used across North Africa, the Middle East, Persia and Ifat; later known as Adal, with varying values. The value of Islamic dirham was 14 qirat, 10 dirham = 7 mithqal, in Islamic law (2.975 gm of silver). In the late Ottoman Empire ( ota, درهم), the standard dirham was 3.207 g; 400 dirhem equal one oka. The Ottoman dirham was based on the Sasanian drachm (in Middle Persian: ''drahm''), which was itself based on the Roman dram/drachm. In Egypt in 1895, it was equivalent to 47.661 troy grains (3.088 g). There is currently a movement within the Islamic world to revive the dirham as a unit of mass for measuring silver, although the exact value is disputed (either 3 or 2.975 grams).
