Metric Mile
A metric mile is a colloquial term used in some countries for the 1500 meters, the premier middle distance running event in international track and field. The term 'metric mile' (0.93 statute miles) was applied to this distance because it approximates one statute mile (1609.344 m). The term is most commonly used in track running, speed skating and swimming. In track running, the 1500 m race became the standard middle distance race in Europe in the late 19th century, and has been the standard distance in the Olympic Games since 1896. Prior to metrication, many tracks in the United States and the Commonwealth of Nations were constructed to the specifications of one quarter of a mile, 440 yards (402.336 m). Thus when the mile was run, the race was a four lap race. The Commonwealth Games officially converted to metric in the mid-1960s. The United States adopted metric rules in the mid to late 1970s, though some tracks are still constructed to be a quarte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1500 Meters
The 1500 metres or 1,500-metre run (typically pronounced 'fifteen-hundred metres') is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983. It is equivalent to 1.5 kilometers or approximately miles. The event is closely associated with its slightly longer cousin, the mile race, from which it derives its nickname "the metric mile". The demands of the race are similar to that of the 800 metres, but with a slightly higher emphasis on aerobic endurance and a slightly lower sprint speed requirement. The 1500 metre race is predominantly aerobic, but anaerobic conditioning is also required. Each lap run during the world-record race run by Hicham El Guerrouj of Morocco in 1998 in Rome, Italy averaged just under 55 seconds (or under 13.8 seconds per 100 metres). 1,500 metres is three and three-quarter laps around a 400-metre track. During the 1970s a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrication In The United States
Metrication (or metrification) is the process of introducing the International System of Units, also known as SI units or the metric system, to replace a jurisdiction's traditional measuring units. U.S. customary units have been defined in terms of metric units since the 19th century, and the SI has been the "preferred system of weights and measures for United States trade and commerce" since 1975 according to United States law. However, conversion was not mandatory and many industries chose not to convert, and U.S. customary units remain in common use in many industries as well as in governmental use (for example, speed limits are still posted in miles per hour). Unlike other countries, there is no governmental or major social desire to implement further metrication. Although customary units are used more often than metric units in the U.S., the SI system is used extensively in some fields such as science, medicine, electronics, the military, automobile production and repai ...

Sport Of Athletics Terminology
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a ''match'') is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a r ...

Units Of Length
A unit of length refers to any arbitrarily chosen and accepted reference standard for measurement of length. The most common units in modern use are the metric units, used in every country globally. In the United States the U.S. customary units are also in use. British Imperial units are still used for some purposes in the United Kingdom and some other countries. The metric system is sub-divided into SI and non-SI units. Metric system SI The base unit in the International System of Units (SI) is the metre, defined as "the length of the path travelled by light in vacuum during a time interval of seconds." It is approximately equal to . Other SI units are derived from the metre by adding prefixes, as in millimetre or kilometre, thus producing systematic decimal multiples and submultiples of the base unit that span many orders of magnitude. For example, a kilometre is . Non-SI In the centimetre–gram–second system of units, the basic unit of length is the centimetre, ...

Metrication
Metrication or metrification is the act or process of converting to the metric system of measurement. All over the world, countries have transitioned from local and traditional units of measurement to the metric system. This process began in France during the 1790s, and is still continuing more than 200 years later, with the modern International System of Units, as the metric system has not yet been fully adopted in all countries and areas. Overview Most countries now have the metric system as their official system of weights and measures. Some have adopted it as their official system but have not yet completed the process of metrication. Some others have not made any commitment to adopting it. There is not a general consensus in the sources as to the number of countries that fall into each of these categories. According to a 2011 doctoral dissertation by Hector Vera, as of 2010, a total of seven countries had not "adopted the metric system as their exclusive system of measure ...

Metric Foot
ISO 2848 (''Building construction – Modular coordination – Principles and rules)'' is an international standard for the construction industry that describes the aims of modular coordination and gives the rules to be used in establishing the dimensions and positioning of buildings and their components. Overview ISO 2848:1984, published by International Organization for Standardization, is an ISO standard used by the construction industry. Adherence to the standard means that major dimensions such as grid lines on drawings, distances between wall centres or surfaces, widths of shelves and kitchen components are multiples of the basic module. Definitions ISO 2848 it is based on multiples of 300 mm and 600 mm. As dimensions increase, preference is given to lengths which are multiples of 3 (see ), 6, 12, 15, 30 and 60 basic modules. For smaller dimensions, the submodular increments M (see ) and M are preferred. The numbers 300 and 600 were chosen beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Federation Of State High School Associations
The National Federation of State High School Associations (NFHS) is the body that writes the rules of competition for most high school sports and activities in the United States. NFHS's headquarters are located in White River State Park in Indianapolis, Indiana. Member and affiliate associations Over 19,500 high schools belong to associations that are members of the NFHS. Most high schools, whether public or private, belong to their state's high school association; in turn, each state association belongs to the NFHS. However, in states that have separate associations for public and non-public high schools, only the public-school bodies are full NFHS members. For example, the Texas University Interscholastic League (public schools, with non-public schools generally not allowed) is a full member; the largest association governing non-public schools, the Texas Association of Private and Parochial Schools, is an affiliate member, while other governing bodies are not NFHS memb ...

Distance Medley Relay
The distance medley relay (DMR) is an athletic event in which four athletes compete as part of a relay. With its inclusion in the IAAF World Relays program, the IAAF announced on May 1, 2015 that the event would be an official world record event. Unlike most track relays, each member of the team runs a different distance. A distance medley relay is made up of a 1200-meter leg (three laps on a standard 400 meter track), a 400-meter leg (one lap), an 800-meter leg (two laps), and a 1600-meter leg (four laps) in that order. The total distance run is 4000 meters, or nearly 2.5 miles. Aside from the 400 meter segment, which is a sprint, all legs are a middle distance run. Prior to going metric, the distance medley relay consisted of a 440-yard leg, an 880-yard leg, a 1320-yard leg and a one-mile leg. The total distance for the old distance medley relay was 4400 yards and the total distance for the current metric distance medley relay is 4374.45 yards - slightly over 25 yards shorter t ...

400 metres
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete. Like other sprint disciplines, the 400 m involves the use of starting blocks. The runners take up position in the blocks on the 'ready' command, adopt a more efficient starting posture which isometrically preloads their muscles on the 'set' command, and stride forwards from the blocks upon hearing the starter's pistol. The blocks allow the runners to begin more powerfully and thereb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Customary Units
United States customary units form a system of Units of measurement, measurement units commonly used in the United States and Territories of the United States, U.S. territories since being standardized and adopted in 1832. The United States customary system (USCS or USC) developed from English units which were in use in the British Empire before the U.S. became an independent country. The United Kingdom's system of measures was overhauled in 1824 to create the imperial system, which was officially adopted in 1826, changing the definitions of some of its units. Consequently, while many U.S. units are essentially similar to their imperial counterparts, there are significant comparison of the imperial and US customary measurement systems, differences between the systems. The majority of U.S. customary units were redefined in terms of the metre, meter and kilogram with the Mendenhall Order of 1893 and, in practice, for many years before.Thomas Corwin Mendenhall, T.C.
