• 
  

  Symbol: lb (from Latin libra)

Nanogram [ng]

The nanogram is a metric unit of mass equal to one-billionth of a gram.

  1 nanogram = 0.000000001 grams = 10⁻⁹ grams

  
  
• 
  

  1 nanogram = 10⁻¹² kilograms

  
  
• 
  

  Symbol: ng

  
  

Key Facts:

• 
  

  Used in fields like biochemistry, pharmacology, and environmental science to measure extremely small masses (e.g., toxins, DNA quantities)

  
  
• 
  

  The prefix "nano-" means $10^{-9}$ (one billionth)

  
  
• 
  

  Smaller than micrograms and widely used for precision measurements at molecular scales

  
  

The nanogram allows scientists to quantify minute amounts of substances with great accuracy.
