Fathom (US Survey)


The fathom (US survey) is a unit of length used in U.S. surveying and nautical contexts, defined as exactly 6 US survey feet. Since one US survey foot is approximately 0.3048006096 meters, the US survey fathom measures about 1.828804 meters.


Like the international fathom, it is primarily used to measure water depths and underwater distances in marine navigation and surveying.


Key details:



  • 1 US survey fathom = 6 US survey feet



  • 1 US survey fathom ≈ 1.828804 meters



  • 1 fathom = 2 yards



Though the difference between the US survey fathom and the international fathom is very small, the US survey units are being phased out in favor of international standards, but they still appear in some legal and historical surveying documents.



Pole


A pole is another traditional unit of length equivalent to a rod or perch. It measures exactly 16.5 feet, 5.5 yards, or about 5.0292 meters.


The pole has been used historically in land measurement and surveying, especially in England and the United States. Like the rod and perch, it helped standardize measurements of fields, plots, and boundaries before the adoption of metric units.


Key conversions:



  • 1 pole = 16.5 feet



  • 1 pole = 5.5 yards



  • 1 pole ≈ 5.0292 meters



  • 4 poles = 1 chain



  • 40 poles = 1 furlong



Though largely replaced by modern units, the pole remains a notable term in historical surveying and land records.
