Barleycorn

A barleycorn is an old English unit of length, traditionally based on the length of a grain of barley. It is defined as exactly 1/3 of an inch or approximately 8.47 millimeters.

Historically, the barleycorn was used for measuring small lengths and was also the basis for the inch, which was originally considered to be three barleycorns long. It played a role in various traditional measurements, including shoe sizing in English-speaking countries, where shoe sizes were sometimes expressed in barleycorn units.

Although obsolete as a formal unit, the barleycorn remains culturally significant, especially in shoe sizing systems.

Summary:

• 
  

  1 barleycorn = 1/3 inch ≈ 8.47 mm

  
  
• 
  

  Based on the length of a grain of barley

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.
