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.

Pole

A pole is another traditional unit of length equivalent to a rod or perch. It measures exactly 16.5 feet, 5.5 yards, or about 5.0292 meters.

The pole has been used historically in land measurement and surveying, especially in England and the United States. Like the rod and perch, it helped standardize measurements of fields, plots, and boundaries before the adoption of metric units.

Key conversions:

• 
  

  1 pole = 16.5 feet

  
  
• 
  

  1 pole = 5.5 yards

  
  
• 
  

  1 pole ≈ 5.0292 meters

  
  
• 
  

  4 poles = 1 chain

  
  
• 
  

  40 poles = 1 furlong

  
  

Though largely replaced by modern units, the pole remains a notable term in historical surveying and land records.
