Convert length and distance units — meters, feet, inches, kilometers, miles, light years and more.
| Unit | Name | Value |
|---|---|---|
| 0.001 mi | 0.008 fur | |
| 0.01 mi | 0.08 fur | |
| 0.1 mi | 0.8 fur | |
| 1 mi | 8 fur | |
| 5 mi | 40 fur | |
| 10 mi | 80 fur | |
| 50 mi | 400 fur | |
| 100 mi | 800 fur | |
| 1000 mi | 8000 fur |
Multiply the number of Miles by 8 to get Furlongs. Formula: fur = mi × 8. Example: 10 mi × 8 = 80 fur. To reverse, divide Furlongs by 8 to get Miles.
| Mile (mi) | Furlong (fur) |
|---|---|
| 0.001 mi | 0.008 fur |
| 0.01 mi | 0.08 fur |
| 0.1 mi | 0.8 fur |
| 0.5 mi | 4 fur |
| 1 mi | 8 fur |
| 2 mi | 16 fur |
| 5 mi | 40 fur |
| 10 mi | 80 fur |
| 20 mi | 160 fur |
| 50 mi | 400 fur |
| 100 mi | 800 fur |
| 250 mi | 2000 fur |
| 500 mi | 4000 fur |
| 1000 mi | 8000 fur |
| 10000 mi | 80000 fur |
To convert Mile to Furlong, multiply by 8. Example: 10 mi = 80 fur
To convert Furlong back to Mile, divide by 8 (multiply by 0.125). Use the swap button above.
Start with 100 Miles = 800 fur as your reference point. Scale up or down from there.
1 mile = 8 furlongs exactly — the most important ratio in horse racing. The Kentucky Derby is 10 furlongs (1.25 miles), the Belmont Stakes is 12 furlongs (1.5 miles). Every US and UK race distance is defined by this relationship.
Early American surveys used furlongs and miles interchangeably. Surveyors and historians converting between the two use the clean 8:1 ratio — 1 mile = 8 furlongs — for quick field calculations and record cross-referencing.
Historic English milestone inscriptions and county maps express distances in miles and furlongs. Heritage groups and local historians convert between the two when interpreting and reproducing historic route documentation.
The 8-furlongs-to-a-mile relationship is taught in UK primary schools as a key imperial measurement fact. Converting between miles and furlongs is a standard exercise in UK Key Stage 2 maths curriculum.
Traditional fell races and cross-country courses in the UK are described in miles and furlongs. Race organisers convert between the two when producing metric-equivalent course descriptions for international entrants.
Canal lock distances and coaching route milestones in the UK used miles and furlongs. Waterway restoration engineers and heritage researchers convert between the two when working with original survey and engineering records.
The Mile is a unit of Length measurement (symbol: mi). 1 mi = 8 fur. Used in scientific and practical Length measurement applications.
The Furlong is a unit of Length measurement (symbol: fur). It is part of an internationally recognised measurement system used alongside the Mile.
The mile traces back to the Roman 'mille passuum' — a thousand paces of a marching legionary, standardised at 5,000 Roman feet. When the Romans left Britain, the English statute mile evolved independently. Parliament fixed it at 5,280 feet (8 furlongs) in 1593 — deliberately chosen to align with the furlong system used in land measurement. The US adopted the statute mile from the British and never metricated road distances. Today only three countries — the US, Liberia, and Myanmar — still officially use miles for road distances.
The furlong — from Old English 'furlang', meaning furrow-long — was the standard length of one furrow ploughed by an ox team. It dates to at least 8th-century England. 10 chains = 1 furlong, 8 furlongs = 1 mile exactly. Today it survives almost exclusively in horse racing, the official distance unit in the UK, Ireland, and Australia.
Common use: Mile to Furlong conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
