Using the international definition of the shipyard as exactly 0.9144 meters, one furlong is 201,168 meters and five furlongs are about 1 kilometer (exactly 1.00584 km). Definition of unit (furlong [international])Size> Furlong is a traditional unit of distance. Long before the Norman conquest in 1066, the Saxon peasants of England measured distance in stems and furlongs and areas in acres. The word « furlong », from the Old English fuhrlang, means « the length of a furrow »; It represents the distance that a team of oxen could travel without interruption. One furlong is equivalent to 40 stems, which is exactly 10 chains, 220 yards, 660 feet or 1/8 of a mile. A furlong is exactly 201,168 meters, so a dash of 200 meters travels a distance very close to a furlong. The duration of horse races is often given in furlongs. After the fall of the Western Roman Empire, medieval Europe continued the Roman system, which diversified people, leading to serious complications in trade, taxation, etc. Around the year 1300, England standardized a long list of measures by royal decree.
Important units of distance and length at that time included the foot, yard, pole (or pole), furlong, and mile. The stem was defined as 5 + 1⁄2 yards or 16 + 1⁄2 feet, and the mile was eight furlongs, so the definition of furlong became 40 stems and that of the mile 5,280 feet (eight furlongs/mile times 40 stems/furlong times 16 + 1⁄2 feet/stem). In the United States, some states use older definitions for surveying purposes, resulting in variations in furlong length of two parts per million, or about 0.4 millimeters (1⁄64 inches). This variation is too small to have practical consequences in most applications. The standard linear measure in the imperial system was the mile, which was divided into furlongs, chains, yards, feet and inches. The definition of furlong differs slightly depending on whether it is defined on the basis of the international shipyard or the American hydrographic foot. The international shipyard is defined as 0.9144 meters. The United States does not formally define survey sites, but on the basis of the survey foot, which is equal to 0.30480061 meters, the « survey site » is 0.91440183 yards. The forest of the town of Bangor in Bangor, Maine, has marked its trail system in miles and furlongs. In the rest of the world, furlong has a very limited use, with the notable exception of horse racing in most English-speaking countries, including Canada and the United States.
Distances for horse racing in Australia were converted to metric values in 1972,[6] but in the United Kingdom,[7] Ireland, Canada and the United States, races are still expressed in miles and furlongs. In addition, distances along English-language canals navigated by narrow boats are usually expressed in miles and furlongs. In Myanmar, furlongs are currently used in conjunction with kilometres to indicate distances on road signs. Milestones on the Yangon-Mandalay Highway consume miles and furlongs. Under the early Anglo-Saxons, staff were the basic unit of surveying. A furlong was 40 stems; one morning 4 times 40 stems or 4 stems times 1 furlong and therefore 160 square stems; There are 10 acres in a square furlong. At that time, the Saxons used the North German foot, which was about 10% longer than the foot of the 1959 international agreement. When England moved to a shorter foot in the late 13th century, stems and furlongs remained unchanged as property boundaries were already defined in stems and furlongs. The only thing that changed was the number of feet and yards in a stem or furlong and the number of square feet and square meters in an acre.
The definition of the rod has increased from 15 old feet to 16 + 1⁄2 new feet or from 5 old yards to 5 + 1⁄2 new yards. Furlong went from 600 old feet to 660 new feet or from 200 old yards to 220 new yards. The morning went from 36,000 old square feet to 43,560 new square feet, or from 4,000 old square feet to 4,840 new square meters. [4] In practice, the difference in the measurement of furlong, based on the difference between the international shipyard and the survey foot, is too small to have significant consequences. Since survey measures generally cover very large areas with varying conditions anyway, it is expected that the best-reported survey data will have some degree of inaccuracy that would not really be distinguishable from an inaccuracy resulting from the slight difference in the definitions of furlong. Definition of unit (Fathom [old])Size >A breaststroke is a unit of measurement equal to 2 yards or 6 feet or 1.8288 meters. The name of the unit is derived from the old English word fæthm, which means « outstretched arms », which was the original definition of the measurement of unity.
