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.

Slug

The slug is a unit of mass used primarily in the U.S. customary system and British engineering contexts.

• 
  

  1 slug = 32.174 pounds (lb) (mass)

  
  
• 
  

  Equivalent to approximately 14.5939 kilograms (kg)

  
  
• 
  

  Defined so that when a force of one pound-force (lbf) acts on a mass of one slug, it accelerates at 1 ft/s² (using $F = ma$ in imperial units).

  
  

Key Facts:

• 
  

  Used mainly in physics and engineering for calculations involving Newton’s second law in imperial units

  
  
• 
  

  Allows consistent use of pound-force and pound-mass without extra conversion factors

  
  
• 
  

  Useful in dynamics, ballistics, and engineering mechanics

  
  

The slug bridges the gap between force and mass in the imperial system, making calculations easier when using pound-force units.
