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.

Milligram (mg)

A milligram is a unit of mass in the metric system, equal to one-thousandth of a gram:

• 
  

  1 milligram = 0.001 grams = 10⁻⁶ kilograms

  
  
• 
  

  Symbol: mg

  
  
• 
  

  Commonly used in medicine, nutrition, and science to measure very small quantities (e.g., dosage of medication, vitamin content, or chemical substances).

  
  

Key Facts:

• 
  

  1 mg = 0.001 g

  
  
• 
  

  1,000 mg = 1 g

  
  
• 
  

  Ideal for measuring very small masses precisely

  
  
• 
  

  Standard in healthcare, pharmacology, and lab work

  
  

The milligram allows for accurate, detailed mass measurement at small scales.
