Furrow-long: the strip an ox team plowed before resting, fixed into the land system forever - ten chains or forty rods to the furlong, and a field one chain wide by one furlong long is exactly one acre. Racing keeps the unit because every distance under the mile is a whole number of furlongs. The customary length definitions: NIST unit conversion.
The farm-and-track family: hands to inches measures the horse that runs the distance, miles to km bridges to metric, and the miles table lines up the whole ladder.

A furlong is one eighth of a mile - 220 yards, 660 feet, 201.168 meters, exact. The name is just furrow-long: the length a team of oxen plowed before resting, which is why the unit is older than the mile it lives inside and why horse racing never gave it up. Type either number and the converter lands the other.

Racing keeps the furlong because races shorter than a mile need finer steps than miles give: sprints at 5 to 7 furlongs, the Kentucky Derby at ten, the Belmont marathon at twelve. The ladder underneath is pure farm geometry - ten chains or forty rods to the furlong, and a strip one furlong long by one chain wide is exactly one acre. The table runs the distances a racecard actually prints.

How to use

  1. Type the furlongs from a racecard - miles appear instantly, or run the reverse.
  2. Read the table for the racing landmarks: five furlongs is the shortest common sprint, eight is the mile, ten is the Derby.
  3. Chain and rod arithmetic still hides inside the unit: one furlong is ten chains, and the acre was surveyed as one chain wide by one furlong long.

Frequently asked questions

How many miles is a furlong?

Exactly one eighth - 0.125 miles, 220 yards, 660 feet, 201.168 meters. The furlong was fixed before the mile was: plowmen standardized the furrow length first, and the statute mile of 5,280 feet was later built out of eight of them. No rounding anywhere in the ladder, which is why surveyors kept it working long after coaches stopped.

Why does horse racing use furlongs?

Tradition, and a usable scale. Races under a mile would be awkward fractions - a six-furlong sprint is three quarters of a mile, and racecards print 6f, not 0.75 mi. The furlong gives every distance below the mile a whole number, the same way minutes serve the hour. American and British racing still schedule everything in furlongs for exactly this reason.

How long is the Kentucky Derby in furlongs?

Ten furlongs - a mile and a quarter, run at Churchill Downs on the first Saturday in May. The Belmont Stakes, the longest Triple Crown leg, is twelve furlongs (a mile and a half); classic European cups sit at the same twelve. When a commentator says a horse is stretching out from seven to nine furlongs, this converter is the translate button.

What is a furlong in chains and rods?

Ten chains - the surveyor's 66-foot chain - or forty rods. That chain arithmetic is not a curiosity: an acre is defined as one chain wide by one furlong long (66 by 660 feet, 43,560 square feet), so the fields the units came from are the units themselves laid side by side. The furlong is the load-bearing wall of the old land system.

Where does the word come from?

Furrow-long - one length of a plowed furrow. An ox team worked a strip as long as it could before the turn, and that working length hardened into the standard. It is the same farm-floor logic as the fathom's rope and the league's hour-walk: units cut from the shape of the day's work, kept alive by the one sport that still runs the distance.
