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.
Five Roman feet made the pace (passus), equivalent to 1.48 metres, or 4.86 feet. The most frequently used itinerary measures were the furlong or stade (stadium), the mile (mille passus), and the league (leuga). The stade consisted of 625 feet (185 metres, or 606.9 feet), or 125 paces, and was equal to one-eighth mile.
