Fingerbreadth

A fingerbreadth is a traditional unit of length based on the width of a human finger, often used in historical and informal measurements. It typically measures about ¾ inch (approximately 19 millimeters), though it can vary depending on the person and context.

Fingerbreadths were commonly used in tailoring, medicine, and everyday life to estimate small lengths before standardized units became widespread.

Key points:

• 
  

  Approximately ¾ inch (19 mm)

  
  
• 
  

  Based on the width of a finger

  
  
• 
  

  Used in historical measurements and everyday approximations

  
  
• 
  

  Part of body-based units like handbreadth and span

  
  

Fingerbreadth remains a handy reference for rough estimates even today.

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.
