What is a US survey fathom used for?

It is a nautical length unit used primarily in measuring water depths, line lengths, and in hydrographic surveys, especially in legacy or historical contexts.

What is the link unit?

The link is a historic English unit of length used in surveying, equal to 1/100 of Gunter's chain and primarily found in 18th–19th century land measurement records.

Why convert fathoms to links?

Converting fathoms to links allows integration and interpretation of legacy nautical depth measurements with historical land surveying data.
