Atomic Mass Unit [u]

The atomic mass unit (u), also known as the unified atomic mass unit or dalton (Da), is a standard unit of mass used to express atomic and molecular weights.

• 
  

  1 u = 1/12 the mass of a carbon-12 atom

  
  
• 
  

  1 u ≈ 1.66053906660 × 10⁻²⁷ kilograms

  
  
• 
  

  Symbol: u or Da

  
  

Key Facts:

• 
  

  Used to measure the mass of atoms, molecules, and subatomic particles

  
  
• 
  

  1 hydrogen atom ≈ 1 u

  
  
• 
  

  Mass of a proton ≈ 1.007 u, neutron ≈ 1.008 u

  
  
• 
  

  Simplifies comparison of atomic-scale masses in chemistry and physics

  
  

The atomic mass unit provides a convenient and consistent way to express and compare very small masses at the atomic and molecular scale.

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.
