Fathom (US Survey)

The fathom (US survey) is a unit of length used in U.S. surveying and nautical contexts, defined as exactly 6 US survey feet. Since one US survey foot is approximately 0.3048006096 meters, the US survey fathom measures about 1.828804 meters.

Like the international fathom, it is primarily used to measure water depths and underwater distances in marine navigation and surveying.

Key details:

• 
  

  1 US survey fathom = 6 US survey feet

  
  
• 
  

  1 US survey fathom ≈ 1.828804 meters

  
  
• 
  

  1 fathom = 2 yards

  
  

Though the difference between the US survey fathom and the international fathom is very small, the US survey units are being phased out in favor of international standards, but they still appear in some legal and historical surveying documents.

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.
