Multiply the number of Furlongs by 0.108622 to get Nautical Miles. Formula: nmi = fur × 0.108622. Example: 10 fur × 0.108622 = 1.08622 nmi. To reverse, divide Nautical Miles by 0.108622 to get Furlongs.

To convert Furlong to Nautical Mile, multiply by 0.108622. Example: 10 fur = 1.08622 nmi
To convert Nautical Mile back to Furlong, divide by 0.108622 (multiply by 9.20624). Use the swap button above.
Start with 100 Furlongs = 10.8622 nmi as your reference point. Scale up or down from there.
Racecourses on coastal sites — like Goodwood near the English Channel — use furlongs for race distances while coastguard and marine safety authorities describe the same area in nautical miles for maritime planning.
Victorian coastal surveys recorded shoreline land distances in furlongs while offshore depth and channel distances used nautical miles. Researchers integrating both datasets convert between the two legacy units.
Offshore wind farms sited adjacent to agricultural land described in furlongs use nautical miles for marine consenting. Environmental impact assessments reference both units and require consistent cross-unit conversion.
Historians studying coastal farming communities encounter both furlongs (land tenure records) and nautical miles (fishing rights, maritime boundaries) in the same archival collections requiring cross-unit conversion.
1 furlong = 0.1086 nautical miles — roughly one-ninth of a nautical mile. Educators use this comparison to show how land and sea measurement systems, though historically separate, have a convenient approximate ratio.
Complete unit converters include furlong-to-nautical-mile to ensure no gap exists for researchers working with combined land and maritime survey records from the British imperial era.
The Furlong is a unit of Length measurement (symbol: fur). 1 fur = 0.108622 nmi. Used in scientific and practical Length measurement applications.
The Nautical Mile is a unit of Length measurement (symbol: nmi). 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 foundational to the open-field system of medieval agriculture. The furlong's elegant internal ratios were carefully defined: 10 chains = 1 furlong, 8 furlongs = 1 statute mile. Today it survives almost exclusively in horse racing, where it remains the official distance unit in the UK, Ireland, Australia, and several other countries.
The nautical mile was defined by Earth's geography — one minute of arc of latitude along a meridian, approximately 1,852 metres. This made it ideal for navigation: on a nautical chart, one nautical mile equals one arcminute, allowing direct distance measurement with dividers. The International Hydrographic Conference standardised it at exactly 1,852 metres in 1929. It is universally used in maritime and aviation navigation — the only two domains that never adopted kilometres for operational distances.
Common use: Furlong to Nautical Mile conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
