Convert length and distance units — meters, feet, inches, kilometers, miles, light years and more.
| Unit | Name | Value |
|---|---|---|
| 0.001 fur | 0.01 chain | |
| 0.01 fur | 0.1 chain | |
| 0.1 fur | 1 chain | |
| 1 fur | 10 chain | |
| 5 fur | 50 chain | |
| 10 fur | 100 chain | |
| 50 fur | 500 chain | |
| 100 fur | 1000 chain | |
| 1000 fur | 10000 chain |
Multiply the number of Furlongs by 10 to get Chains. Formula: chain = fur × 10. Example: 10 fur × 10 = 100 chain. To reverse, divide Chains by 10 to get Furlongs.
| Furlong (fur) | Chain (chain) |
|---|---|
| 0.001 fur | 0.01 chain |
| 0.01 fur | 0.1 chain |
| 0.1 fur | 1 chain |
| 0.5 fur | 5 chain |
| 1 fur | 10 chain |
| 2 fur | 20 chain |
| 5 fur | 50 chain |
| 10 fur | 100 chain |
| 20 fur | 200 chain |
| 50 fur | 500 chain |
| 100 fur | 1000 chain |
| 250 fur | 2500 chain |
| 500 fur | 5000 chain |
| 1000 fur | 10000 chain |
| 10000 fur | 100000 chain |
To convert Furlong to Chain, multiply by 10. Example: 10 fur = 100 chain
To convert Chain back to Furlong, divide by 10 (multiply by 0.1). Use the swap button above.
Start with 100 Furlongs = 1000 chain as your reference point. Scale up or down from there.
1 furlong = 10 chains exactly — the most fundamental relationship in British imperial land measurement. Racecourse designers use chains for precise layout surveying and convert to furlongs for official race distance certification and signage.
British land surveyors still use chains and furlongs in historic records and legal documents. Surveyors converting between the two — with the clean 10:1 ratio — check historic boundary descriptions against modern GPS coordinates.
Enclosure maps and field surveys from 17th–19th century England describe field dimensions in both chains and furlongs. Historians and archaeologists mapping these fields convert between the two using the 10:1 ratio.
British railways officially measure distances in miles and chains. Since 10 chains = 1 furlong and 8 furlongs = 1 mile, railway engineers occasionally convert between chains and furlongs when working with historic distance records.
The 10:1 furlong-to-chain ratio is one of the cleanest in the imperial system and is used in education to show students that pre-metric measurement, while complex overall, had elegant internal relationships within specific domains.
Orienteers using OS maps with chain-based National Grid sometimes convert to furlongs when describing route sections in terms of racecourse distances — a comparison familiar to UK outdoor enthusiasts.
The Furlong is a unit of Length measurement (symbol: fur). 1 fur = 10 chain. Used in scientific and practical Length measurement applications.
The Chain is a unit of Length measurement (symbol: chain). It is part of an internationally recognised measurement system used alongside the Furlong.
The furlong — from Old English 'furlang', meaning furrow-long — was the standard length of one furrow ploughed by an ox team without resting, typically 220 yards. It dates to at least 8th-century England and was used to lay out the open-field system of medieval agriculture. The furlong's relationship to other units was carefully defined: 10 chains = 1 furlong, 8 furlongs = 1 mile. Today it survives almost exclusively in horse racing, where it remains the official distance unit in the UK, Ireland, and Australia.
Edmund Gunter invented the surveyor's chain in 1620. His design — 100 links totalling exactly 66 feet — was brilliantly chosen: 10 chains × 10 chains = 1 acre, making area calculation trivially simple in the field. 80 chains = 1 mile, 10 chains = 1 furlong. The chain became the standard survey unit across the British Empire and is written into American law — the US Public Land Survey System still divides land using chains and links.
Common use: Furlong to Chain conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
