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.

Quintal (Metric) [cwt]

The metric quintal is a unit of mass equal to 100 kilograms. It is widely used in agriculture and commerce for measuring bulk goods like grains, produce, and livestock feed.

Though called "quintal," it differs from other regional versions like the British hundredweight (cwt). In some countries, especially those using the metric system, the quintal serves as a convenient intermediate unit between kilograms and metric tons.

Summary:

• 
  

  1 metric quintal = 100 kg

  
  
• 
  

  Common in farming and trade for easy large-quantity measurements
