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 (Long) [ton (UK)]

The long ton, also known as the imperial ton or British ton, is a unit of mass traditionally used in the United Kingdom and some Commonwealth countries.

• 
  

  1 long ton = 2,240 pounds

  
  
• 
  

  1 long ton ≈ 1,016.0469 kilograms

  
  
• 
  

  Symbol: often written as ton (UK) or long ton

  
  
• 
  

  Historically used in shipping, freight, and coal industries in the UK.

  
  

Key Facts:

• 
  

  1 long ton = 2,240 lb

  
  
• 
  

  ≈ 1,016.05 kg

  
  
• 
  

  Heavier than the short ton (US, 2,000 lb)

  
  
• 
  

  Slightly heavier than the metric ton (1,000 kg)

  
  

Though largely replaced by the metric ton in most official UK uses, the long ton is still referenced in certain industries and historical contexts.
