Hectogram [hg]

The hectogram is a metric unit of mass equal to one hundred grams.

• 
  

  1 hectogram = 100 grams

  
  
• 
  

  1 hectogram = 0.1 kilograms

  
  
• 
  

  Symbol: hg

  
  

Key Facts:

• 
  

  Commonly used in some countries for food packaging and grocery measurements

  
  
• 
  

  The prefix "hecto-" means $10^2$ (one hundred)

  
  
• 
  

  Larger than a gram but smaller than a kilogram

  
  

The hectogram is a convenient unit for measuring moderate amounts of mass in everyday situations.

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
