What is a fathom (US survey)?

It is a non-SI unit of length equal to 6 US survey feet, used mainly in nautical contexts for measuring water depths and line lengths.

How long is a rod in meters?

A rod is exactly 5.0292 meters and is a traditional English unit used for land measurement.

Why convert fathoms to rods?

Converting fathoms to rods helps translate maritime length measurements into traditional land units, useful for integrating legacy survey data.
