What is a fathom (US survey) used for?

The US survey fathom is primarily used for measuring water depths, anchor cables, and mooring lines in nautical and hydrographic contexts.

Why is the reed considered an obsolete unit?

The reed is obsolete because its exact length varied by place and time, and modern measurements have standardized more consistent units.

Can I use this conversion for precise legal or archaeological measurements?

This conversion helps interpret historical data, but due to varying reed lengths and fathom definitions, cross-checking is advised for precise work.
