Chain

A chain is a unit of length traditionally used in land surveying. The most common version is the Gunter’s chain, which equals 66 feet or 22 yards, approximately 20.1168 meters.

The chain was introduced by English clergyman Edmund Gunter in the 17th century to simplify land measurement. One chain consists of 100 links, each 0.66 feet long. It became a standard unit in British and American land surveying and was instrumental in defining land areas, especially in the U.S. Public Land Survey System.

Key Conversions:

• 
  

  1 chain = 66 feet

  
  
• 
  

  1 chain = 22 yards

  
  
• 
  

  1 chain ≈ 20.1168 meters

  
  
• 
  

  10 chains = 1 furlong

  
  
• 
  

  80 chains = 1 mile

  
  

Though now largely replaced by metric units and modern surveying tools, the chain still appears in older land deeds, maps, and rural property descriptions.

Microinch

A microinch is a very small unit of length used primarily in precision engineering and manufacturing. It equals one-millionth of an inch (0.000001 inch), which is approximately 0.0254 micrometers (µm).

Microinches are used to measure extremely fine tolerances, surface finishes, and thicknesses in high-precision machining, electronics, and materials science.

Key facts:

• 
  

  1 microinch = 0.000001 inch

  
  
• 
  

  1 microinch ≈ 0.0254 micrometers (µm)

  
  
• 
  

  Used in precision engineering for very small measurements

  
  
• 
  

  Allows for accurate description of surface roughness and thickness

  
  

The microinch is essential in fields requiring ultra-fine measurements where standard units like the inch or millimeter are too large.
