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.

Hundredweight (UK)

The hundredweight (UK), also called the long hundredweight or imperial hundredweight, is a British unit of mass equal to 112 pounds (approximately 50.8 kilograms).

It is part of the imperial system and is traditionally used in the UK and some Commonwealth countries for measuring goods, especially in agriculture and shipping.

Summary:

• 
  

  1 UK hundredweight = 112 pounds (about 50.8 kg)

  
  
• 
  

  Used in the UK for trade and bulk measurements
