What is a fathom (US survey)?

A US survey fathom is a non-SI unit of length equal to 6 US survey feet or about 1.8288 meters, traditionally used in nautical and hydrographic measurements.

What is the dekameter unit?

A dekameter is an SI-derived length unit equal to 10 meters, often applied to medium-scale distances in surveying, meteorology, and infrastructure.

Why convert from fathom (US survey) to dekameter?

Conversion enables translation of traditional nautical measurements into modern metric units, facilitating interoperability between legacy and current surveying or mapping data.
