Electron Mass (Rest)

The rest mass of an electron is the intrinsic mass of an electron when it is at rest (not moving relative to an observer).

Its value is approximately 9.109 × 10⁻³¹ kilograms (or about 0.511 MeV/c² in energy units).

This tiny mass is fundamental to atomic and particle physics, influencing how electrons behave in atoms and electric currents.

Summary:

• 
  

  Rest mass ≈ 9.109 × 10⁻³¹ kg

  
  
• 
  

  Equivalent to about 0.511 MeV/c²

  
  
• 
  

  Fundamental property of the electron in physics

  
  

Ton (Short) [ton (US)]

The short ton, also known as the US ton, is a unit of mass used primarily in the United States.

• 
  

  1 short ton = 2,000 pounds

  
  
• 
  

  1 short ton ≈ 907.1847 kilograms

  
  
• 
  

  Symbol: often written as ton (US) or simply ton in American usage

  
  
• 
  

  Commonly used in U.S. industries like agriculture, mining, and freight

  
  

Key Facts:

• 
  

  1 short ton = 2,000 lb

  
  
• 
  

  ≈ 907.18 kg

  
  
• 
  

  Not the same as the metric ton (1,000 kg) or long ton (UK, 2,240 lb)

  
  
• 
  

  Used for large-scale weight measurements in the U.S.

  
  

The short ton is part of the U.S. customary system and is widely used in domestic trade and industry.
