Attogram [ag]

The attogram is a metric unit of mass equal to one-quintillionth of a gram.

• 
  

  1 attogram = 0.000000000000000001 grams = 10⁻¹⁸ grams

  
  
• 
  

  1 attogram = 10⁻²¹ kilograms

  
  
• 
  

  Symbol: ag

  
  

Key Facts:

• 
  

  Used in cutting-edge scientific fields like nanotechnology, physics, and molecular science

  
  
• 
  

  The prefix "atto-" means $10^{-18}$ (one quintillionth)

  
  
• 
  

  Enables measurement of extraordinarily tiny masses, such as single molecules or atoms

  
  

The attogram is vital for quantifying masses at the smallest scales currently measurable in science.

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.
