    Sure, it's a 16th of a mile. City blocks in Chicago (where I grew up) were two furlongs long. And more recently, the Kentucky Derby (and other horse races) was measured innfurlongs. Furlongs are convenient since a square, two furlongs on a side, contains 10 acres, which are city blocks in Chicago.A quarter section is four furlings on a side. And, of course there are 10 chains in a furlong.
