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:

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.

Arpent

An arpent is a traditional unit of length and area used primarily in French-speaking regions, especially in parts of Canada (like Quebec) and Louisiana in the United States. It originated in France and was commonly used in land measurement and agriculture.

• 
  

  As a length, one arpent is approximately 192 feet (about 58.47 meters), though it varies regionally.

  
  
• 
  

  As an area, an arpent is roughly equal to 0.84 acres or about 3,400 square meters.

  
  

The arpent was important for defining land parcels during French colonial times and is still referenced in legal land descriptions in some areas today.
