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.
A mile is eight furlongs. A furlong is ten chains. A chain is twenty-two yards, which happens to be the length of a cricket pitch. [math]1\rm{mile}=8\times10\times22=1760\rm{yards}[/math] Pseudo-random factors like eight, ten, and twenty-two are why the Imperial system of weights and measures has lost so convincingly to the metric system.
