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.

Tonne [t]

The tonne, also known as the metric ton, is a unit of mass in the metric system equal to 1,000 kilograms or 1 megagram. It is widely used around the world for measuring large quantities of mass, such as in shipping, industry, and science.

The tonne is slightly larger than the US short ton (2,000 pounds) and the UK long ton (2,240 pounds).

Summary:

• 
  

  1 tonne = 1,000 kilograms (about 2,204.62 pounds)

  
  
• 
  

  Standard unit for large-scale mass measurements globally
