Units explained
Link
A link is an Imperial unit of length equal to 7.92 inches (201.168 mm) — exactly 1/100 of a surveyor's chain. It is the smallest unit in the chain-based survey measurement system.
The link was defined by Edmund Gunter in 1620 as part of his 22-yard surveying chain. He divided the chain into 100 links specifically to enable easy decimal arithmetic when computing parcel areas.
Links appear in historical US and UK land survey documents (especially pre-1900). Modern surveyors generally use feet or meters but legacy deed records and government land surveys still cite acreage in chains and links.
Defined by Edmund Gunter in 1620; standardised as 7.92 inches via the chain definition; became exact via the 1959 International Yard and Pound Agreement.
Fathom
A fathom is an Imperial unit of length equal to 6 feet or exactly 1.8288 meters. It is used almost exclusively for measuring water depth in maritime contexts.
The fathom derives from the Old English word fæthm, meaning "the embracing arms" — the distance between the fingertips of a person's outstretched arms. Standardized at 6 feet in English maritime tradition.
Fathoms are used in nautical depth charts, scuba diving, oceanography, and maritime literature. Despite metrication efforts, fathoms remain common in English-language nautical charts and recreational diving.
Old English origin (predating 1066); standardized at 6 feet by English maritime tradition; fixed at 1.8288 m exactly via the 1959 International Yard and Pound Agreement.

Step-by-step: convert links to fathoms
- Write down the value in links (lk).
- Multiply that value by the factor 0.11.
- The product is the equivalent value in fathoms (ftm).
- To reverse, multiply the fathom value by 9.0909090909.
Worked examples
Example 1 — Convert 1 lk to ftm:
1 × 0.11 = 0.11 ftm
Example 2 — Convert 100 lk to ftm:
100 × 0.11 = 11 ftm
Real-world example — Reference scenario in case of fallback
Conversion between human-scale length units is the everyday workflow of architecture, athletics, and apparel design — three of the most common contexts that span metric and imperial systems.
1 lk × 0.11 = 0.11 ftm
Real-world example — Adult height conversion
A 1.8-link-tall person measures a value in fathoms that converts the height to the unit favoured by American forms, schools, or driver's licences. This is daily routine for anyone living between metric and imperial systems.
1.8 lk × 0.11 = 0.198 ftm
Real-world example — Fabric purchase length
Two links of fabric equals a value in fathoms essential for tailors and textile buyers sourcing material from international suppliers that quote in different units.
2 lk × 0.11 = 0.22 ftm
