What is a fathom (US survey)?

It is a non-SI length unit equal to 6 US survey feet, primarily used in nautical and hydrographic measurements.

What is a rod (US survey)?

A rod is a traditional surveying length unit equal to exactly 16.5 US survey feet, used in land measurement and legal property descriptions.

Why convert fathoms to rods?

Converting fathoms to rods helps translate underwater and nautical measurements into traditional land surveying units to integrate maritime data with land-based maps.
