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.

Foot (US Survey)

The US survey foot is a unit of length used historically in the United States for land surveying and mapping. It is defined as exactly 1200/3937 meters, which is approximately 0.3048006096 meters. This makes it very slightly longer than the international foot, which is exactly 0.3048 meters.

The US survey foot was established to maintain consistency with earlier land surveys and legal descriptions in the U.S. It was used extensively in the Public Land Survey System and other cadastral surveys.

Key points:

• 
  

  1 US survey foot = 1200/3937 meters ≈ 0.3048006096 meters

  
  
• 
  

  Slightly longer than the international foot by about 0.0006 millimeters

  
  
•
