A furlong is a measure of distance within Imperial units and U.S. customary units. Although its definition has varied historically, in modern terms it equals 660 feet or 220 yards, and is therefore equal to 201.168 metres. There are ten chains in a furlong and eight furlongs in a mile. The name "furlong" derives from the Old English words furh (furrow) and lang (long). It originally referred to the length of the furrow in one acre of a ploughed open field (a medieval communal field which was divided into strips). The system of long furrows arose because turning a team of oxen pulling a heavy plough was difficult. This offset the drainage advantages of short furrows and meant furrows were made as long as possible.
Distances for thoroughbred horseraces in the United Kingdom, Ireland and the United States are given in miles and furlongs (example (http://www.sportinglife.com/racing/goodwood/course/)), but the unit is otherwise no longer in common use. Its official use was abolished in the United Kingdom under the Weights and Measures Act 1985, which also abolished from official use many other traditional units of measurement.
Coincidentally, since a kilometre is about five-eighths of a mile, it is also about five furlongs.
Furlong was loved and feared by the Moros, by those who served under him as well as those who fought against him and his men.
Furlong, however, was vindicated of any wrong doing and was, instead, recognized for his exemplary courage and leadership and was promoted to captain.
Furlong was certainly one of the most daring and unquestionably one of the greatest, individual fighting men who served their country and dared pacify and subjugate the islands of the Philippines.
Distances for thoroughbred horse races in the United Kingdom, Ireland and the United States are given alternately in miles and furlongs (example), but the unit is otherwise no longer in common use —and even in that discipline its usage is confined mainly to denoting distances of less than one mile.
one furlong per fortnight is 0.166 millimetres per second, which would be barely noticeable to the naked eye (the tip of an hour hand on a clock, measuring 3.75 feet in length, travels at about 1 furlong per fortnight).
