What is a chain used for?

A chain is a traditional unit of length primarily used in cadastral surveying, land measurement, and interpreting historical survey records.

How does the US survey fathom differ from other fathoms?

The US survey fathom is slightly different from the international fathom, being exactly 6 US survey feet and used mainly in nautical and hydrographic contexts.

Why convert chain to fathom (US survey)?

Converting from chain to US survey fathom helps translate land survey measurements into water depth or maritime length units, facilitating the understanding of legacy data.
