Line (length)
The line (abbreviated L or l or ‴ or lin.) was a small English unit of length, variously reckoned as , , , or of an inch. It was not included among the units authorized as the British Imperial system in 1824. Size The line was not recognized by any statute of the English Parliament but was usually understood as of a barleycorn, which itself was recognized by statute as of an inch. The line was eventually decimalized as of an inch, without recourse to barleycorns. The US button trade uses the same or a similar term but defined as one-fortieth of the US-customary inch (making a button-maker's line equal to 0.635 mm). In use Botanists formerly used the units (usually as inch) to measure the size of plant parts. Linnaeus's ''Philosophia botanica'' (1751) includes the Linea in its summary of units of measurements, defining it as "Linea una Mensurae parisinae"; Stearns gives its length as 2.25 mm. Even after metrication, British botanists continued to employ tool ...

English Units
English units are the units of measurement used in England up to 1826 (when they were replaced by Imperial units), which evolved as a combination of the Anglo-Saxon and Roman systems of units. Various standards have applied to English units at different times, in different places, and for different applications. Use of the term "English units" can be ambiguous, as, in addition to the meaning used in this article, it is sometimes used to refer to the units of the descendent Imperial system as well to those of the descendant system of United States customary units. The two main sets of English units were the Winchester Units, used from 1495 to 1587, as affirmed by King Henry VII, and the Exchequer Standards, in use from 1588 to 1825, as defined by Queen Elizabeth I. In England (and the British Empire), English units were replaced by Imperial units in 1824 (effective 1 January 1826) by a Weights and Measures Act, which retained many though not all of the unit names and redefin ...

German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Weights And Measures Acts Of The United Kingdom
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 ...

Imperial Units
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the related but differing system of customary units of the United States. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empire, notably Canada. The modern UK legislation defining the imperial system of units is given in the Weights and Measures Act ...

German Units Of Measurement
The units of measurement of German-speaking countries consist of a variety of units, with varying local standard definitions. While many were made redundant with the introduction of the metric system, some of these units are still used in everyday speech and even in stores and on street markets as shorthand for similar amounts in the metric system. For example, some customers ask for one pound (''ein Pfund'') of something when they want 500 grams. The metric system became compulsory on 1 January 1872, in Germany and on 1 January 1876, in Austria. Some obsolete German units have names similar to units that were traditionally used in other countries, and that are still used in a limited number of cases in the United Kingdom (imperial units) and fully in the United States ( United States customary units). German system Before the introduction of the metric system in German, almost every town had its own definitions of the units shown below. Often towns posted local definitio ...

Portuguese Customary Units
Portuguese customary units were used in Portugal, Brazil and other parts of the Portuguese Empire until the adoption of the metric system in the 19th century. The various systems of weights and measures used in Portugal until the 19th century combine remote Roman influences with medieval influences from northern Europe and Islam. These influences are obvious in the names of the units. The measurement units themselves were, in many cases, inherited from a distant past. From the Romans, Portugal inherited names like ( la, palmus), ( la, cubitus), , ( la, uncia), ( la, modius), ( la, quartarius), ( la, sextarius). From medieval northern Europe, Portugal inherited names like ( en, mark, french: marc), ( en, bushel, french: boisseau), ( en, tun, french: tonneau), ( en, pint, french: pinte), (Fr. french: chopine), etc. From the Moors, Portugal receive unit names like (Arabic language, Arabic: ), (Arabic language, Arabic: ), (Arabic language, Arabic: ), (Arabic language, Ar ...

French Units Of Measurement
200px, Table of the measuring units used in the 17th century at Pernes-les-Fontaines in the covered market at Provence-Alpes-Côte d'Azur Regions of France">region of southeastern France France has a unique history of Unit of measurement, units of measurement due to its radical decision to invent and adopt the metric system after the French Revolution. 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 ...

Peter The Great
Peter I ( – ), most commonly known as Peter the Great,) or Pyotr Alekséyevich ( rus, Пётр Алексе́евич, p=ˈpʲɵtr ɐlʲɪˈksʲejɪvʲɪtɕ, , group=pron was a Russian monarch who ruled the Tsardom of Russia from to 1721 and subsequently the Russian Empire until his death in 1725, jointly ruling with his elder half-brother, Ivan V until 1696. He is primarily credited with the modernisation of the country, transforming it into a European power. Through a number of successful wars, he captured ports at Azov and the Baltic Sea, laying the groundwork for the Imperial Russian Navy, ending uncontested Swedish supremacy in the Baltic and beginning the Tsardom's expansion into a much larger empire that became a major European power. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lasting ...

Obsolete Russian Units Of Measurement
A native system of weights and measures was used in Imperial Russia and after the Russian Revolution, but it was abandoned after 21 July 1925, when the Soviet Union adopted the metric system, per the order of the Council of People's Commissars. The Tatar system is very similar to the Russian one, but some names are different. The Polish system is also very close to the Russian. The system existed since ancient Rus', but under Peter the Great, the Russian units were redefined relative to the English system.Шостьин Н. А. Очерки истории русской метрологии XI – начала XX века. М.: 1975. Until Peter the Great the system also used Cyrillic numerals, and only in the 18th century did Peter the Great replace it with the Hindu–Arabic numeral system. Length The basic unit was the Russian ell, called the ''arshin'', which came into use in the 16th century. It was standardized by Peter the Great in the 18th century to measure exactly ...

M2 Browning Machine Gun
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ...

Mosin–Nagant
The Mosin–Nagant is a five-shot, bolt-action, internal magazine–fed military rifle. Known officially as the 3-line rifle M1891 and informally in Russia and former Soviet Union as Mosin's rifle ( ru , винтовка Мосина, ISO 9: ), it is primarily found chambered for its original 7.62×54mmR cartridge. Developed from 1882 to 1891, it was used by the armed forces of the Russian Empire, the Soviet Union and various other states. It is one of the most mass-produced military bolt-action rifles in history, with over 37 million units produced since 1891. In spite of its age, it has been used in various conflicts around the world up to the present day. History Initial design and tests During the Russo-Ottoman War of 1877–1878, Russian troops armed mostly with Berdan single-shot rifles suffered heavy casualties against Turkish troops equipped with Winchester repeating rifles, particularly at the bloody Siege of Pleven. This showed Russian commanders the need to mode ...
