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.

Electron Mass (Rest)

The rest mass of an electron is the intrinsic mass of an electron when it is at rest (not moving relative to an observer).

Its value is approximately 9.109 × 10⁻³¹ kilograms (or about 0.511 MeV/c² in energy units).

This tiny mass is fundamental to atomic and particle physics, influencing how electrons behave in atoms and electric currents.

Summary:

• 
  

  Rest mass ≈ 9.109 × 10⁻³¹ kg

  
  
• 
  

  Equivalent to about 0.511 MeV/c²

  
  
• 
  

  Fundamental property of the electron in physics
