A furlong is a measure of distance in imperial units and U.S. customary units equal to one-eighth of a mile, equivalent to 660 feet, 220 yards, 40 rods, or 10 chains. Using the international definition of the inch as exactly 25.4 millimetres, one furlong is 201.168 metres.
When the British began using the mile, they related it to the furlong, which was a very common length used in agriculture. In 1592, the British Parliament decided that a mile would equal eight furlongs. One furlong equals 660 feet, and eight furlongs equal 5,280 feet. According to Mental Floss there are three countries that still do not officially use the metric system, as of 2014: the United States, Liberia and Burma.
