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.


Barleycorn


A barleycorn is an old English unit of length, traditionally based on the length of a grain of barley. It is defined as exactly 1/3 of an inch or approximately 8.47 millimeters.


Historically, the barleycorn was used for measuring small lengths and was also the basis for the inch, which was originally considered to be three barleycorns long. It played a role in various traditional measurements, including shoe sizing in English-speaking countries, where shoe sizes were sometimes expressed in barleycorn units.


Although obsolete as a formal unit, the barleycorn remains culturally significant, especially in shoe sizing systems.


Summary:



  • 1 barleycorn = 1/3 inch ≈ 8.47 mm



  • Based on the length of a grain of barley



  • Used historically in small measurements and shoe sizing



  • Mostly of historical and cultural interest today
