What is a famn used for?

A famn is a maritime unit traditionally used to express depths and nautical distances, as well as lengths of shipboard ropes and cables.

Why use the US survey inch instead of the international inch?

The US survey inch is a legacy surveying unit important for interpreting and converting historical US geodetic and cadastral records.

Can I use this converter for modern measurement needs?

This tool is primarily designed for converting historical and maritime lengths; modern applications usually use standard international units.
