- Convert quickly: 8 furlongs = 1 mile = 1.609 km.
- Furlongs are used almost exclusively in horse racing — elsewhere they are largely historical.
Common Mistakes
Avoid these- Assuming furlongs appear in modern road distances — they do not.
- Confusing furlongs with fathoms (a nautical depth unit).
- Using 200 m as a shortcut when accuracy matters — the true value is 201.168 m.
About Furlong and Kilometer
What is the Furlong?
The furlong equals exactly 201.168 meters or one eighth of a mile (220 yards). The unit's name comes from the Old English 'furh' (furrow) and 'lang' (long), reflecting its origin as the length of a furrow that an ox team could plow without resting. Formalized in medieval England, the furlong was standardized as 40 rods or 660 feet during agricultural land measurement. Today, the furlong's primary modern use is in horse racing across the United Kingdom, the United States, and several Commonwealth countries — race distances are quoted in furlongs (a 6-furlong sprint is ¾ of a mile). It also appears in old land deeds, particularly in Britain. The furlong relates to the mile (8 furlongs = 1 mile), the yard (220 yd = 1 furlong), and the meter (≈201 m).
- Flat racing and National Hunt distances in the UK
- Thoroughbred racing in the US and Canada
- Historical land measurement in England
The Epsom Derby is run over 1 mile and 4 furlongs (about 2.4 km). The Kentucky Derby is 10 furlongs.
What is the Kilometer?
The kilometer equals exactly 1,000 meters and is the international standard unit for road distances, geography, and travel. Adopted as part of the metric system in the 1790s, it became the dominant road-distance unit worldwide except in the United States, the United Kingdom (which uses miles for road signs), and Myanmar. Speed limits across Europe, Asia, Australia, Africa, and Latin America are expressed in km/h. The kilometer's relationship to the meter is decimal and exact, making it ideal for scientific work. A kilometer takes a healthy adult about 12 minutes to walk and roughly 1,250 average steps. Geographic distances — from city blocks to airline routes — are typically given in kilometers, with the Earth's equatorial circumference measuring approximately 40,075 km.
