Examples
-
1 fathom (US survey) equals 2.5714337143 Russian archin.
-
3 fathoms (US survey) convert to approximately 7.714301143 Russian archin by multiplying by 2.5714337143.
Common Use Cases
-
Recording water depths and line lengths in maritime operations using fathoms.
-
Measuring lengths of textiles and cloth in pre-metric Russian trade in archins.

What is a US survey fathom used for?
-
It is a nautical length unit used primarily for measuring water depths, anchor cables, and mooring lines in maritime and hydrographic contexts.
-
Why convert fathoms to Russian archins?
-
Converting helps translate nautical depths and legacy survey data into historical Russian length measurements useful for research, restoration, and trade analysis.
-
Is the Russian archin still in use today?
-
No, the Russian archin is an obsolete unit that was used before metrication in Russia, mainly for trade and crafts.
