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.
Foot (US Survey)
The US survey foot is a unit of length used historically in the United States for land surveying and mapping. It is defined as exactly 1200/3937 meters, which is approximately 0.3048006096 meters. This makes it very slightly longer than the international foot, which is exactly 0.3048 meters.
The US survey foot was established to maintain consistency with earlier land surveys and legal descriptions in the U.S. It was used extensively in the Public Land Survey System and other cadastral surveys.
Key points:
1 US survey foot = 1200/3937 meters ≈ 0.3048006096 meters
Slightly longer than the international foot by about 0.0006 millimeters
Used primarily in land surveying and legal documents
As of recent years, the US has been phasing out the US survey foot in favor of the international foot for standardization.
Though nearly identical to the international foot, the US survey foot remains important for understanding older land records and measurements.
