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.

Long Cubit

The long cubit is an ancient unit of length that is a variation of the standard cubit, measuring from the elbow to the tip of the middle finger. The long cubit is longer than the common cubit, typically about 21 inches (approximately 53 centimeters).

It was used in ancient civilizations such as Egypt and Mesopotamia for construction, land measurement, and crafts, especially when more precision or a larger unit was needed.

Key points:

• 
  

  Long cubit ≈ 21 inches (53 cm)

  
  
• 
  

  Longer than the standard cubit (usually about 18 inches)

  
  
• 
  

  Used in ancient architecture and surveying

  
  
• 
  

  Provided a larger base unit for measurements in construction

  
  

The long cubit helped ancient builders and surveyors manage larger scales while still relying on the human body as a reference.
