Classical Electron Radius

The classical electron radius is a theoretical length scale associated with the electron, derived from classical electromagnetism. It represents the size of a hypothetical sphere where the electron’s electrostatic energy equals its rest mass energy.

• 
  

  Its value is approximately 2.818 × 10⁻¹⁵ meters (about 2.8 femtometers).

  
  
• 
  

  Calculated using fundamental constants: the electron charge, mass, and the speed of light.

  
  
• 
  

  It is not the actual physical size of the electron (which is considered point-like in quantum mechanics), but a useful scale in classical physics.

  
  
• 
  

  Used in scattering theory and classical electron models.

  
  

Key facts:

• 
  

  Classical electron radius ≈ 2.818 × 10⁻¹⁵ m

  
  
• 
  

  Represents an electromagnetic length scale, not a physical size

  
  
• 
  

  Important in classical models of electron behavior

  
  

This radius helps bridge classical and quantum views of particle physics.

Kiloyard

A kiloyard is a less commonly used unit of length that equals 1,000 yards. Since one yard is exactly 0.9144 meters, a kiloyard is equivalent to 914.4 meters or 0.9144 kilometers.

While not widely used in everyday measurements or scientific contexts, the kiloyard may occasionally appear in specialized fields like military applications, ballistics, or older engineering texts where large distances were measured in yards. It follows the metric-style prefix "kilo-" (meaning one thousand) combined with the imperial unit "yard."

Conversion:

• 
  

  1 kiloyard = 1,000 yards

  
  
• 
  

  1 kiloyard = 914.4 meters

  
  
• 
  

  1 kiloyard ≈ 0.568 miles

  
  

Due to the dominance of the metric system and the more common use of miles for longer imperial distances, the kiloyard remains a rare and non-standard unit in most modern contexts.
