Femtogram [fg]

The femtogram is a metric unit of mass equal to one-quadrillionth of a gram.

• 
  

  1 femtogram = 0.000000000000001 grams = 10⁻¹⁵ grams

  
  
• 
  

  1 femtogram = 10⁻¹⁸ kilograms

  Symbol: fg

  
  

Key Facts:

• 
  

  Used in highly sensitive scientific research, including molecular biology, physics, and nanotechnology

  
  
• 
  

  The prefix "femto-" means $10^{-15}$ (one quadrillionth)

  
  
• 
  

  Measures incredibly small masses such as molecules, atoms, and nanoparticles

  
  

The femtogram allows for the detection and measurement of ultrafine masses at the atomic and molecular scale.

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

  
  
•
