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 Comparison of the imperial and US customary measurement systems, related but differing system of United States customary units, customary units of the United States. The imperial units replaced the Winchester measure, 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 metrication, 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 empi ...

Edinburgh College Of Physicians
The Royal College of Physicians of Edinburgh (RCPE) is a medical royal college in Scotland. It is one of three organisations that set the specialty training standards for physicians in the United Kingdom. It was established by royal charter in 1681. The college has over 14,000 fellows and members worldwide, who are entitled to use using the post-nominal MRCP(Edin) or FRCP(Edin). History The RCPE was formed by a royal charter, granted in 1681, with Sir Robert Sibbald recognised as playing a key part in the negotiations. Three applications preceded this and had been unsuccessful. There were 21 original Fellows, eleven of whom were graduates or students of the University of Leiden. The Universities (Scotland) Act 1858 resulted in several items from the college's charter becoming obsolete, and they obtained a further charter on 31 October 1861. In 1920 the college enacted changes that allowed women to be admitted on the same terms as men. The charter was further amended on 7 M ...

Foot (unit)
The foot (standard symbol: ft) is a Units of measurement, unit of length in the imperial units, British imperial and United States customary units, United States customary systems of metrology, measurement. The prime (symbol), prime symbol, , is commonly used to represent the foot. In both customary and imperial units, one foot comprises 12 inches, and one yard comprises three feet. Since international yard and pound, an international agreement in 1959, the foot is defined as equal to exactly 0.3048 meters. Historically, the "foot" was a part of many local systems of units, including the Ancient Greek units of measurement, Greek, Ancient Roman units of measurement, Roman, Chinese units of measurement, Chinese, Units of measurement in France before the French Revolution, French, and English units, English systems. It varied in length from country to country, from city to city, and sometimes from trade to trade. Its length was usually between 250 mm and 335 mm and ...

Hand (unit)
The hand is a non-SI unit of measurement of length standardized to . It is used to measure the height of horses in many English-speaking countries, including Australia, Canada, Republic of Ireland, Ireland, the United Kingdom, and the United States. It was originally based on the breadth of a human hand. The adoption of the Inch#Equivalents, international inch in 1959 allowed for a standardized Imperial and US customary measurement systems#Units of length, imperial form and a Metric system, metric conversion. It may be abbreviated to "h" or "hh". Although measurements between whole hands are usually expressed in what appears to be decimal format, the subdivision of the hand is not decimal but is in radix, base 4, so subdivisions after the radix point are in quarters of a hand, which are inches. Thus, 62 inches is fifteen and a half hands, or 15.2 hh (normally said as "fifteen-two", or occasionally in full as "fifteen hands two inches"). Terminology "Hands" may be abbrevia ...

Inch
The inch (symbol: in or prime (symbol), ) is a Units of measurement, unit of length in the imperial units, British Imperial and the United States customary units, United States customary System of measurement, systems of measurement. It is equal to yard or of a foot (unit), foot. Derived from the Uncia (unit), Roman uncia ("twelfth"), the word ''inch'' is also sometimes used to translate similar units in other measurement systems, anthropic units, usually understood as deriving from the width of the human thumb. Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4Millimetre, mm. Name The English word "inch" () was an early borrowing from Latin ' ("one-twelfth; Roman inch; Roman ounce"). The vowel change from Latin to Old English (which became Modern English ) is known as Germanic umlaut, umlaut. The consonant c ...

Barleycorn (unit)
The barleycorn is an English unit of length equal to of an inch (i.e. about ). It is still used as the basis of shoe sizes in English-speaking countries. History Under the 1300 Composition of Yards and Perches, one of the statutes of uncertain date that was notionally in force until the 1824 Weights and Measures Act, "3 dry and " were to serve as the basis for the inch and thence the larger units of feet, yards, perches and thus of the acre, an important unit of area. The notion of three barleycorns composing an inch certainly predates this statute, however, appearing in the 10th-century Welsh Laws of Hywel Dda. In practice, various weights and measures acts of the English kings were standardized with reference to some particular yard-length iron, brass, or bronze bar held by the king or the Royal Exchequer. The formal barleycorn was of its length. As modern studies show, the actual length of a kernel of barley varies from as short as to as long as depending on the cu ...

Thou (length)
A thousandth of an inch is a derived unit of length in a system of units using inches. Equal to of an inch, a thousandth is commonly called a thou (used for both singular and plural) or, particularly in North America, a mil (plural mils). The words are shortened forms of the English and Latin words for "thousand" ( in Latin). In international engineering contexts, confusion can arise because ''mil'' is a formal unit name in North America but ''mil'' or ''mill'' is also a common colloquial clipped form of millimetre. The units are considerably different: a millimetre is approximately 39 mils. Contexts of use The thou, or mil, is most commonly used in engineering and manufacturing in non-metric countries. For example, in specifying: * The thickness of items such as paper, film, foil, wires, paint coatings, latex gloves, plastic sheeting, and fibers ** For example, most plastic ID cards are about in thickness. ** Card stock thickness in the United States, where mils are also ...

Twip
A twip (abbreviating "twentieth of a point" or "twentieth of an inch point") is a typographical measurement, defined as of a typographical point. One twip is inch, or 17.64 μm. In computing Twips are screen-independent units to ensure that the proportion of screen elements are the same on all display systems. A twip is defined as being of an inch (approximately 17.64 μm). A pixel is a screen-dependent unit, standing for 'picture element'. A pixel is a dot that represents the smallest graphical measurement on a screen. Twips are the default unit of measurement in Visual Basic (version 6 and earlier, prior to VB.NET). Converting between twips and screen pixels is achieved using the TwipsPerPixelX and TwipsPerPixelY properties or the ScaleX and ScaleY methods. Twips can be used with Symbian OS bitmap images for automatic scaling from bitmap pixels to device pixels. They are also used in Rich Text Format from Microsoft for platform-independent exchange and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metres
The metre (or meter in US spelling; symbol: m) is the base unit of length in the International System of Units (SI). Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of of a second, where the second is defined by a hyperfine transition frequency of caesium. The metre was originally defined in 1791 by the French National Assembly as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's polar circumference is approximately . In 1799, the metre was redefined in terms of a prototype metre bar. The bar used was changed in 1889, and in 1960 the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path trav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Crown
The Crown is a political concept used in Commonwealth realms. Depending on the context used, it generally refers to the entirety of the State (polity), state (or in federal realms, the relevant level of government in that state), the executive government specifically or only to the monarch and their Viceroy, direct representatives. The term can be used to refer to the rule of law; or to the functions of executive (government), executive (the Crown-King-in-Council, in-council), legislative (the Crown-in-parliament), and judicial (the Crown on the bench) governance and the civil service. The concept of the Crown as a corporation sole developed first in the Kingdom of England as a separation of the physical crown and property of the kingdom from the person and personal property of the monarch. It spread through English and later British colonisation and developed into an imperial crown, which rooted it in the legal lexicon of all 15 Commonwealth realms, their various dependencies, ...

Medical Act 1858
The Medical Act ( 21 & 22 Vict. c. 90), ''An Act to Regulate the Qualifications of Practitioners in Medicine and Surgery'', also referred to as the Medical Act 1858, was an act of the Parliament of the United Kingdom which created the General Medical Council to regulate doctors in the UK. It is one of the Medical Acts. Describing its purpose, the Act notes that "it is expedient that Persons requiring Medical Aid should be enabled to distinguish qualified from unqualified Practitioners". The act creates the position of Registrar of the General Medical Council – an office still in existence today – whose duty is to keep up-to-date records of those registered to practise medicine and to make them publicly available. The act has now been almost entirely repealed. The current law governing medical regulation is the Medical Act 1983. Under the Poor Law system Boards of Guardians could only employ those qualified in medicine and surgery as Poor Law Doctors. Under a clause i ...
