Miles Per Gallon Equivalent
The mile, sometimes the international mile or statute mile to distinguish it from other miles, is a British imperial unit and United States customary unit of length; both are based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. The statute mile was standardised between the Commonwealth of Nations and the United States by an international agreement in 1959, when it was formally redefined with respect to SI units as exactly . With qualifiers, ''mile'' is also used to describe or translate a wide range of units derived from or roughly equivalent to the Roman mile (roughly ), such as the nautical mile (now exactly), the Italian mile (roughly ), and the Chinese mile (now exactly). The Romans divided their mile into 5,000 (), but the greater importance of furlongs in the Elizabethan-era England meant that the statute mile was made equivalent to or in 1593. This form of the mile then spread across the British Empire, some successor states ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milestone
A milestone is a numbered marker placed on a route such as a road, railway, railway line, canal or border, boundary. They can indicate the distance to towns, cities, and other places or landmarks like Mileage sign, mileage signs; or they can give their position on the route relative to some datum location. On roads they are typically located at the side or in a Central reservation, median or central reservation. They are alternatively known as mile markers (sometimes abbreviated MMs), mileposts or mile posts (sometimes abbreviated MPs). A "kilometric point" is a term used in Metrication, metricated areas, where distances are commonly measured in kilometres instead of miles. "Distance marker" is a generic unit-agnostic term. Milestones are installed to provide linear referencing points along the road. This can be used to reassure travellers that the proper path is being followed, and to indicate either distance travelled or the remaining distance to a destination. Such refer ...

Commonwealth Of Nations
The Commonwealth of Nations, often referred to as the British Commonwealth or simply the Commonwealth, is an International organization, international association of member states of the Commonwealth of Nations, 56 member states, the vast majority of which are former territorial evolution of the British Empire, territories of the British Empire from which it developed. They are connected through their English in the Commonwealth of Nations, use of the English language and cultural and historical ties. The chief institutions of the organisation are the Commonwealth Secretariat, which focuses on intergovernmental relations, and the Commonwealth Foundation, which focuses on non-governmental relations between member nations. Numerous List of Commonwealth organisations, organisations are associated with and operate within the Commonwealth. The Commonwealth dates back to the first half of the 20th century with the decolonisation of the British Empire through increased self-governance ...

International System Of Units
The International System of Units, internationally known by the abbreviation SI (from French ), is the modern form of the metric system and the world's most widely used system of measurement. It is the only system of measurement with official status in nearly every country in the world, employed in science, technology, industry, and everyday commerce. The SI system is coordinated by the International Bureau of Weights and Measures, which is abbreviated BIPM from . The SI comprises a coherent system of units of measurement starting with seven base units, which are the second (symbol s, the unit of time), metre (m, length), kilogram (kg, mass), ampere (A, electric current), kelvin (K, thermodynamic temperature), mole (mol, amount of substance), and candela (cd, luminous intensity). The system can accommodate coherent units for an unlimited number of additional quantities. These are called coherent derived units, which can always be represented as products of powers of ...

North American Datum
The North American Datum (NAD) is the Geodetic datum#Horizontal datum, horizontal datum now used to define the Geodesy, geodetic network in North America. A datum is a formal description of the shape of the Earth along with an "anchor" point for the coordinate system. In surveying, cartography, and land-use planning, two North American Datums are in use for making lateral or "horizontal" measurements: the North American Datum of 1927 (NAD 27) and the North American Datum of 1983 (NAD 83). Both are geodetic reference systems based on slightly different assumptions and measurements. Vertical measurements, based on distances above or below Mean High Water (MHW), are calculated using the North American Vertical Datum of 1988 (NAVD 88). NAD 83, along with NAVD 88, is set to be replaced with a new GPS- and gravimetric geoid model-based geometric reference frame and geopotential datum, potentially Datum of 2022, in 2025.

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

British Empire
The British Empire comprised the dominions, Crown colony, colonies, protectorates, League of Nations mandate, mandates, and other Dependent territory, territories ruled or administered by the United Kingdom and its predecessor states. It began with the English overseas possessions, overseas possessions and trading posts established by Kingdom of England, England in the late 16th and early 17th centuries, and colonisation attempts by Kingdom of Scotland, Scotland during the 17th century. At its height in the 19th and early 20th centuries, it became the List of largest empires, largest empire in history and, for a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, of the world population at the time, and by 1920, it covered , of the Earth's total land area.

Statute
A statute is a law or formal written enactment of a legislature. Statutes typically declare, command or prohibit something. Statutes are distinguished from court law and unwritten law (also known as common law) in that they are the expressed will of a legislative body, whether that be on the behalf of a country, state or province, county, municipality, or so on. Depending on the legal system, a statute may also be referred to as an "act." Etymology The word appears in use in English as early as the 14th century. "Statute" and earlier English spellings were derived from the Old French words ''statut'', ''estatut'', ''estatu,'' meaning "(royal) promulgation, (legal) statute." These terms were in turn derived from the Late Latin ''statutum,'' meaning "a law, decree." Publication and organization In virtually all countries, newly enacted statutes are published and distributed so that everyone can look up the statutory law. This can be done in the form of a government gazette, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of England
The Kingdom of England was a sovereign state on the island of Great Britain from the late 9th century, when it was unified from various Heptarchy, Anglo-Saxon kingdoms, until 1 May 1707, when it united with Kingdom of Scotland, Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the Middle Ages, medieval and Early modern period, early modern periods. Beginning in the year 886 Alfred the Great reoccupied London from the Danish Vikings and after this event he declared himself King of the Anglo-Saxons, until his death in 899. During the course of the early tenth century, the various Anglo-Saxons, Anglo-Saxon kingdoms were united by Alfred's descendants Edward the Elder (reigned 899–924) and Æthelstan (reigned 924–939) to form the Kingdom of the English. In 927, Æthelstan conquered the last remaining Viking kingdom, Scandinavian York, York, making him the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Roman Units Of Measurement
The units of measurement of ancient Rome were generally consistent and well documented. Length The basic unit of Roman linear measurement was the ''pes'' (plural: ''pedes'') or Roman foot. Investigation of its relation to the English foot goes back at least to 1647, when John Greaves published his ''Discourse on the Romane foot''. Greaves visited Rome in 1639, and measured, among other things, the foot measure on the tomb of Titus Statilius Aper, that on the statue of Cossutius formerly in the gardens of Angelo Colocci, the congius of Vespasian previously measured by Villalpandus, a number of brass measuring-rods found in the ruins of Rome, the paving-stones of the Pantheon and many other ancient Roman buildings, and the distance between the milestones on the Appian Way. He concluded that the Cossutian foot was the "true" Roman foot, and reported these values compared to the iron standard of the English foot in the Guildhall in London William Smith (1851) gives a value ...

Li (unit)
''Li'' or ri (, ''lǐ'', or , ''shìlǐ''), also known as the Chinese mile, is a traditional Chinese unit of distance. The ''li'' has varied considerably over time but was usually about one third of an English mile and now has a standardized length of a half-kilometer (). This is then divided into 1,500 chi or "Chinese feet". The character 里 combines the characters for "field" ( 田, ''tián'') and "earth" ( 土, ''tǔ''), since it was considered to be about the length of a single village. As late as the 1940s, a "li" did not represent a fixed measure but could be longer or shorter depending on the ''effort'' required to cover the distance. This traditional unit, in terms of historical usage and distance proportion, can be considered the East Asian counterpart to the Western league unit. However, in English '' league'' commonly means "3 miles." There is also another '' li'' (Traditional: 釐, Simplified: 厘, ''lí'') that indicates a unit of length of a ''chi'', but i ...
