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.

Stone (US)

The stone (US) is a unit of weight occasionally used in the United States but much less common than in the UK. In the US, a stone is typically defined as 14 pounds (about 6.35 kilograms), the same as the British stone.

However, the stone is not widely used in American everyday measurements or commerce; it mainly appears in some historical contexts or among communities familiar with British units.

Summary:

• 
  

  1 US stone = 14 pounds (6.35 kg)

  
  
• 
  

  Rarely used in modern US measurements

  
  
• 
  

  Same weight as the British stone
