How to convert Fathom to Foot

Multiply the number of Fathoms by 6 to get Foots. Formula: ft = ftm × 6. Example: 10 ftm × 6 = 60 ft. To reverse, divide Foots by 6 to get Fathoms.

Worked examples

Example 1
1 ftm × 6 = 6 ft
1 Fathom equals 6 Foot.
Example 2
5 ftm × 6 = 30 ft
5 Fathom equals 30 Foot.
Example 3
10 ftm × 6 = 60 ft
10 Fathom equals 60 Foot.
Example 4 — reverse
1 ft = 0.166667 ftm
To convert back from Foot to Fathom, divide by 6 or use the swap button above.

Where fathom to foot conversion is used

Nautical chart reading in the US

US nautical charts show depths in feet and fathoms. American boaters, naval officers, and harbour pilots convert between fathoms and feet constantly when reading charts and communicating depth information.

Fishing & angling

Fishing depth is described in fathoms in offshore fishing tradition, while fishing tackle specifications (line length, rod length) use feet. Anglers convert between fathoms and feet for setting correct fishing depth.

Offshore oil & gas

Offshore drilling operations describe water depth in fathoms in traditional references while engineering drawings for subsea structures use feet — petroleum engineers convert between the two in well planning documents.

Historic shipbuilding

Ship draught (depth below waterline) has historically been measured in feet and fathoms interchangeably. Naval architects and maritime historians convert between fathoms and feet when interpreting historical vessel specifications.

Diving certification

Open water dive tables and certification standards historically use fathoms for depth in some systems, while modern recreational diving limits are expressed in feet — dive instructors convert between the two for student training.

Anchor chain & rope

Anchor chain is sold in lengths of fathoms by tradition but rope and hardware dimensions use feet and inches. Marine equipment suppliers convert fathoms to feet for unified ordering and inventory systems.

Frequently asked questions

About Fathom and Foot

Fathom (ftm)

The Fathom is a unit of Length measurement (symbol: ftm). 1 ftm = 6 ft. Used in scientific and practical Length measurement applications.

Foot (ft)

The Foot is a unit of Length measurement (symbol: ft). It is part of an internationally recognised measurement system used alongside the Fathom.

History & origin

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 foot is one of humanity's oldest measurement units, used by ancient Egyptians, Greeks, and Romans. The English statute foot was standardised at 12 inches in 1305 under King Edward I, finally fixed as exactly 0.3048 metres under the International Yard and Pound Agreement of 1959, signed by the US, UK, Canada, Australia, and South Africa. Today the foot remains official in the US, UK for road distances, and international aviation.

Common use: Fathom to Foot conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
