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.

Vara Castellana

The vara castellana is a traditional Spanish unit of length that was widely used in Spain and its former colonies. It is roughly equivalent to 0.8359 meters (about 32.9 inches).

The vara castellana was commonly used in land measurement, construction, and textiles. Its length could vary slightly by region and time, but the standardized vara castellana became an important reference for legal and commercial measurements.

Key points:

• 
  

  1 vara castellana ≈ 0.8359 meters (32.9 inches)

  
  
• 
  

  Used extensively in Spain and Spanish America

  
  
• 
  

  Common in land surveying, building, and textile measurement
