Multiply the number of Fathoms by 0.00909091 to get Furlongs. Formula: fur = ftm × 0.00909091. Example: 10 ftm × 0.00909091 = 0.0909091 fur. To reverse, divide Furlongs by 0.00909091 to get Fathoms.

To convert Fathom to Furlong, multiply by 0.00909091. Example: 10 ftm = 0.0909091 fur
To convert Furlong back to Fathom, divide by 0.00909091 (multiply by 110). Use the swap button above.
Start with 100 Fathoms = 0.909091 fur as your reference point. Scale up or down from there.
1 furlong = 110 fathoms — a clean ratio that makes this conversion useful for teaching how different imperial measurement systems (land surveying and maritime) related to each other before metrication.
Historic coastal surveys used furlongs for shoreline distances and fathoms for offshore depths. Researchers studying historic coastal change convert between the two units when analysing combined land and sea survey records.
Both the fathom and furlong are pre-metric units with rich histories — the fathom from the span of outstretched arms, the furlong from a furrow's length. Historians of measurement compare the two to understand pre-metric systems.
Neither the fathom nor the furlong is in common everyday use. Converting between them requires understanding two obscure imperial units simultaneously — making it a valuable exercise in dimensional analysis for engineering students.
Beach horse racing events use furlongs for race distances while course safety surveys measure water depth in fathoms for events run near the sea — race organisers occasionally need cross-unit conversion.
Complete length converters include fathom-to-furlong for historical completeness — ensuring no gap exists when researchers work with legacy imperial documents where both units appear in the same survey record.
The Fathom is a unit of Length measurement (symbol: ftm). 1 ftm = 0.00909091 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 Fathom.
The fathom derives from the Old English 'fæthm', meaning the span of outstretched arms — roughly 6 feet or 1.8 metres. It was the primary depth measurement unit used by mariners for millennia, recorded in the Bible and used by ancient Greeks. The word 'fathom' also entered English as a verb meaning to understand something deeply — from the idea of plumbing the depths. Despite metrication, fathoms remain on admiralty charts and in nautical tradition worldwide.
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. 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 several other countries.
Common use: Fathom to Furlong conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
