Quarter (US) [qr (US)]

The quarter (US), abbreviated as qr (US), is a unit of weight used primarily in agriculture and commodities trading in the United States. It equals 25 pounds (about 11.34 kilograms).

The quarter is one-quarter of a US hundredweight (100 pounds), making it a convenient subdivision for measuring smaller bulk quantities of goods like grains, livestock, and produce.

Summary:

• 
  

  1 US quarter = 25 pounds (11.34 kg)

  
  
• 
  

  Used mainly in US agricultural and commodity markets

  
  
• 
  

  Represents ¼ of a US hundredweight

  
  

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.
