Mil

A mil is a unit of length commonly used in engineering and manufacturing to measure very small distances, especially thicknesses. It is equal to one-thousandth of an inch (0.001 inch), which is approximately 0.0254 millimeters.

The mil is widely used in industries like plastic film, coatings, wire diameter, and mechanical parts, where precise measurements of thin materials are necessary. It should not be confused with the millimeter, which is 0.001 meters or 1,000 microns — much larger than a mil.

Key points:

• 
  

  1 mil = 0.001 inch = 0.0254 mm

  
  
• 
  

  Used mainly for small thicknesses or diameters

  
  
• 
  

  Common in engineering, manufacturing, and material sciences

  
  
• 
  

  Not to be confused with millimeter (mm)

  
  

The mil remains an important unit in technical fields where fine measurement is critical.

Fermi

A fermi is a unit of length used in nuclear physics to measure extremely small distances, such as the size of atomic nuclei. It is equal to 1 femtometer (fm), which is 10⁻¹⁵ meters.

The unit is named after the Italian physicist Enrico Fermi, known for his work in nuclear physics.

Key facts:

• 
  

  1 fermi = 1 femtometer = 10⁻¹⁵ meters

  
  
• 
  

  Used to measure nuclear dimensions and particle sizes

  
  
• 
  

  Essential in the study of nuclear and particle physics

  
  

The fermi is vital for describing distances at the subatomic scale, much smaller than atoms and molecules.
