The US survey fathom differs slightly from the international fathom; be cautious when converting.
-
Fixed exact conversions may not account for minor discrepancies from historical length standard variations.
Frequently Asked Questions
-
What is an international nautical league?
-
It is a historical maritime length equal to three international nautical miles or 5,556 metres, used to express distances at sea.
-
How does the US survey fathom differ from the international fathom?
-
The US survey fathom equals 6 US survey feet and is slightly different in length from the international fathom, used mainly for hydrographic measurements.
-
Why convert nautical leagues to fathoms?
-
Converting helps translate historical distances into practical measurements for water depths, cable lengths, and facilitates use in modern maritime surveying.
Key Terminology
-
Nautical league (int.)
-
A historical maritime unit equal to three international nautical miles or 5,556 metres, used primarily in older nautical contexts.
-
Fathom (US survey) [fath]
