Furlong (US Survey)


The furlong (US survey) is a traditional unit of distance used in U.S. land surveying, defined as 1/8 of a U.S. survey mile, or exactly 660 U.S. survey feet. Since one U.S. survey foot equals approximately 0.3048006096 meters, the US survey furlong is about 201.1684 meters long.


While the difference between the US survey furlong and the international (standard) furlong is extremely small (just a few micrometers), it was significant in precise land measurements, particularly in legal and cadastral surveying contexts.


Key Conversions:



  • 1 US survey furlong = 660 US survey feet



  • 1 US survey furlong ≈ 220 yards



  • 1 US survey furlong ≈ 201.1684 meters



  • 8 US survey furlongs = 1 US survey mile



As of 2023, the U.S. has officially deprecated the use of the survey foot (and by extension the survey furlong) in favor of the international foot, but it may still appear in historical and legal documents.


Rod


A rod is a traditional unit of length used in land measurement and surveying. It is equal to 16.5 feet, 5.5 yards, or exactly 5.0292 meters.


Also known as a pole or perch, the rod dates back to medieval England and was commonly used for measuring land and agricultural plots. It is closely related to other units such as the chain (which is 4 rods) and the furlong (which is 40 rods).


Key conversions:



  • 1 rod = 16.5 feet



  • 1 rod = 5.5 yards



  • 1 rod = 5.0292 meters



  • 4 rods = 1 chain



  • 40 rods = 1 furlong



Though largely replaced by metric units today, the rod is still occasionally used in surveying and legal descriptions of land, especially in the United States and the UK.
