Charlemagne's Pound
The Carolingian pound ( lat, pondus Caroli, german: Karlspfund), also called Charlemagne's pound or the Charlemagne pound, was a unit of weight that emerged during the reign of Charlemagne. It served both as a trading weight and a coinage weight. It had a mass of about 408 g and was introduced in as part of Charlemagne's monetary reform around AD 793/94. This stipulated that 240 ''denarii'' (= ''pfennigs'') were to be minted from one pound weight of silver. The units of weight that emerged over time as a result of the Carolingian monetary system and its associated pound or ''Karlspfund'', were of great importance for large parts of Europe. The basic features of this monetary system, which was based on the Carolingian pound, continued to exist in England until 1971. Initially, the Carolingian pound was valid across the whole of the Carolingian Empire and, to a lesser extent, in the Holy Roman Empire under the Ottonian dynasty that followed. Under the Salians, who ruled from 1024, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Of Weight
A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present. A multitude of systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system. In trade, weights and measures is often a subject of governmental regulation, to ensure fairness and transparency. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis VI Of France
Louis VI (late 1081 – 1 August 1137), called the Fat (french: link=no, le Gros) or the Fighter (french: link=no, le Batailleur), was King of the Franks from 1108 to 1137. Chronicles called him "King of Saint-Denis". Louis was the first member of the house of Capet to make a lasting contribution to centralizing the institutions of royal power. He spent almost all of his twenty-nine-year reign fighting either the " robber barons" who plagued Paris or the kings of England for their continental possession of Normandy. Nonetheless, Louis VI managed to reinforce his power considerably and became one of the first strong kings of France since the death of Charlemagne in 814. Louis was a warrior-king, but by his forties his weight had become so great that it was increasingly difficult for him to lead in the field (hence the epithet ). Details about his life and person are preserved in the , a panegyric composed by his loyal advisor, Suger, abbot of Saint Denis. Early life Louis was b ...

German Customs Union
The (), or German Customs Union, was a coalition of German states formed to manage tariffs and economic policies within their territories. Organized by the 1833 treaties, it formally started on 1 January 1834. However, its foundations had been in development from 1818 with the creation of a variety of custom unions among the German states. By 1866, the included most of the German states. The Zollverein was not part of the German Confederation (1815-1866). The foundation of the was the first instance in history in which independent states consummated a full economic union without the simultaneous creation of a political federation or union. Prussia was the primary driver behind the creation of the customs union. Austria was excluded from the because of its highly protectionist trade policy, the unwillingness to split its customs territory into the separate Austrian, Hungarian and Galician-Lodomerian ones, as well as due to opposition of Prince von Metternich to the idea. ...

Coefficient Of Variation
In probability theory and statistics, the coefficient of variation (CV), also known as relative standard deviation (RSD), is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage, and is defined as the ratio of the standard deviation \sigma to the mean \mu (or its absolute value, The CV or RSD is widely used in analytical chemistry to express the precision and repeatability of an assay. It is also commonly used in fields such as engineering or physics when doing quality assurance studies and ANOVA gauge R&R, by economists and investors in economic models, and in neuroscience. Definition The coefficient of variation (CV) is defined as the ratio of the standard deviation \ \sigma to the mean \ \mu , c_ = \frac. It shows the extent of variability in relation to the mean of the population. The coefficient of variation should be computed only for data measured on scales that have a meaningful zer ...

Apothecary Weight
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 sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Weights And Measures (Austria)
Austrian units of measurement were used in Austria until the adoption of the metric system. History In 1756, the ruling Archduchess of Austria, Maria Theresa, ordered that the Viennese ''klafter'' as well as its multiples and fractions, should be the state-defined measure of length in the Archduchy of Austria and the Kingdom of Hungary. The Viennese cubit, that is 1 of the Roman cubit (cubitus or elbow), was also used as a measure of length. The law should also have applied to the Lands of the Bohemian Crown, of which Maria Theresa was queen. However, the traditional Roman foot remained in common use in Prague. When the metric system was introduced by law on 23 July 1871 (which became obligatory on 1 January 1876), History of the metric system#The German Zollverein the length of the ''klafter'' (kl) was established as exactly 1.89648384 metres. Measures Austrian post-mile, police-mile, geographic mile = 3,910 Viennese ''klafters''. References *''The information ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grain (weight)
A grain is a Physical unit, 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 (text), 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 English mass units, traditional English weight systems, and is the only unit that is equal throu ...

Metrology
Metrology is the scientific study of measurement. It establishes a common understanding of units, crucial in linking human activities. Modern metrology has its roots in the French Revolution's political motivation to standardise units in France when a length standard taken from a natural source was proposed. This led to the creation of the decimal-based metric system in 1795, establishing a set of standards for other types of measurements. Several other countries adopted the metric system between 1795 and 1875; to ensure conformity between the countries, the Bureau International des Poids et Mesures (BIPM) was established by the Metre Convention. This has evolved into the International System of Units (SI) as a result of a resolution at the 11th General Conference on Weights and Measures (CGPM) in 1960. Metrology is divided into three basic overlapping activities: * The definition of units of measurement * The realisation of these units of measurement in practice * Traceabi ...

Henry IV Of England
Henry IV ( April 1367 – 20 March 1413), also known as Henry Bolingbroke, was King of England from 1399 to 1413. He asserted the claim of his grandfather King Edward III, a maternal grandson of Philip IV of France, to the Kingdom of France. Henry was the first English ruler since the Norman Conquest, over three hundred years prior, whose mother tongue was English rather than French. Henry was the son of John of Gaunt, Duke of Lancaster, himself the son of Edward III. John of Gaunt was a power in England during the reign of Henry's cousin Richard II. Henry was involved in the revolt of the Lords Appellant against Richard in 1388, resulting in his exile. After John died in 1399, Richard blocked Henry's inheritance of his father's duchy. That year, Henry rallied a group of supporters, overthrew and imprisoned Richard II, and usurped the throne, actions that later would lead to what is termed the Wars of the Roses and a more stabilized monarchy. As king, Henry faced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troy Weight
Troy weight is a system of Physical unit, 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 (unit), 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, 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 Henry IV of England#Relationship with Richard II, Earl of Derby. Charles Moore Watson (1844–1916) proposes an alternative etymology: ''The Assize o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Weights And Measures (France)

In the Ancien régime and until 1795, France used a system of measures that had many of the characteristics of the modern Imperial System of units but with no unified system. There was widespread abuse of the king's standards, to the extent that the ''lieue'' could vary from 3.268 km in Beauce to 5.849 km in Provence. During the revolutionary era and motivated in part by the inhomegeneity of the old system, France switched to the first version of the metric system. This system was not well received by the public, and between 1812 and 1837, the country used the ''mesures usuelles'' – traditional names were restored, bu ...
