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.

Ton (Long) [ton (UK)]

The long ton, also known as the imperial ton or British ton, is a unit of mass traditionally used in the United Kingdom and some Commonwealth countries.
