Pound [lb or lbs]

The pound is a unit of mass commonly used in the imperial and U.S. customary systems.

• 
  

  1 pound = 0.45359237 kilograms (exact, by definition)

  
  
• 
  

  Symbol: lb (from Latin libra)

  
  
• 
  

  Widely used in the United States and a few other countries for body weight, food, and general mass measurements.

  
  
• 
  

  There are 16 ounces (oz) in 1 pound.

  
  

Key Facts:

• 
  

  1 lb = 16 oz

  
  
• 
  

  1 lb ≈ 0.454 kg

  
  
• 
  

  Common in everyday U.S. and UK usage

  
  
• 
  

  Not an SI unit, but legally defined for trade and commerce

  
  

While the pound is not part of the metric system, it remains a familiar unit in daily life for many people, especially in the U.S. and UK.

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
