What is a chain (US survey)?

A chain (US survey) is a traditional unit of length equal to 66 US survey feet and subdivided into 100 links, commonly used historically in U.S. land surveying.

Why convert chains to fathoms?

Converting chains to fathoms helps translate land survey measurements into nautical units for applications like maritime navigation and historical research.

Are fathoms used outside nautical contexts?

Fathoms are primarily used in nautical contexts such as measuring water depth and cable lengths, and are less common in modern terrestrial surveying.
