What is a Furlong and a Roman Mile?
The Furlong (symbol fur) is a unit of length in the imperial and U.S. customary systems of measurement. It is defined as exactly one-eighth of a mile (1/8 mi). This is equivalent to 220 yards (yd), 660 feet (ft), or precisely 201.168 meters (m).
The Roman Mile (mille passus, meaning "thousand paces"; symbol m.p.) was the standard Roman unit for measuring longer distances.
It was defined as 1,000 Roman paces (passus).
Since one passus (a double step) was equal to 5 Roman feet (pes), the Roman mile was equivalent to:
- 1,000 paces (passus)
- 5,000 Roman feet (pedes)
The exact length varied slightly depending on the precise definition of the Roman foot used, but it is typically estimated as:
- Approximately 1,480 meters (m)
- Approximately 1.48 kilometers (km)
- Approximately 0.919 statute miles (mi)
- Approximately 4,856 feet (ft) (using a common estimate for the Roman foot)
Note: The Furlong is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Roman Mile belongs to the imperial/US customary system.
History of the Furlong and Roman Mile
The name "furlong" derives from the Old English words furh (furrow) and lang (long). It originally represented the approximate distance a team of oxen could plow without rest within a typical English open field system. It also related to the traditional size of an acre, which was conceived as an area of land one furlong long and one chain (66 feet) wide. The furlong was standardized as 40 rods (a rod being 5.5 yards) or 10 chains. While historically significant in agriculture and land surveying, its use has greatly diminished with the adoption of metric units and the decline of the imperial system for general measurements.
The Roman mile was established during the Roman Republic and Empire and was used extensively throughout Roman territories for measuring roads, distances between cities, and military movements. Roman roads were famously marked with milestones (miliarium) indicating the distance in Roman miles, often back to the Milliarium Aureum (Golden Milestone) in the Forum Romanum.
The Roman mile significantly influenced the development of the mile unit in other countries, including the English statute mile, although the lengths eventually diverged.
Common Uses for furlongs and Roman miles
Explore the typical applications for both Furlong (imperial/US) and Roman Mile (imperial/US) to understand their common contexts.
Common Uses for furlongs
Although largely obsolete for general use, the furlong persists in specific contexts:
- Horse Racing: Its most prominent modern use is in measuring race distances in countries like the United Kingdom, Ireland, the United States, and Canada. Race lengths are frequently given in furlongs (e.g., a 6-furlong sprint).
- Historical Context: Encountered in historical documents, land deeds, and literature referring to land measurement or travel distances in imperial units.
- Figurative Language: Occasionally used informally or figuratively to denote a distance, though this is rare.
- Myanmar (Burma): The furlong remains in common use in Myanmar as a customary unit alongside the mile.
Common Uses for Roman miles
- Historical Measurement: Used ubiquitously in the Roman Empire for all land distances.
- Historical Texts: Essential for understanding distances mentioned in Roman literature, historical accounts, and geographical works.
- Archaeology: Used to interpret Roman road networks, milestone placements, and site layouts.
Frequently Asked Questions
Questions About Furlong (fur)
How many furlongs are in a mile?

- 660 feet (ft)
- 201.168 meters (m) (exactly)
Where is the furlong used most often today?

About Roman Mile (m.p.)
How long was a Roman Mile compared to a modern mile?
A Roman mile (approx. 1480 m) was shorter than the modern international statute mile (1609.344 m). A Roman mile is about 92% the length of a modern statute mile.
What does 'mille passus' mean?
It's Latin for "a thousand paces". Mille means thousand, and passus refers to the Roman pace (a double step of 5 Roman feet).
How many feet were in a Roman Mile?
There were 5,000 Roman feet (pedes) in one Roman mile.
Is the Roman Mile still used?
No, the Roman mile is obsolete and not used for any modern measurements. It is purely a historical unit. Modern distances are measured in kilometers or statute miles.
