Ton-Force (Long) [tonf (UK)]

The long ton-force (also called the UK ton-force) is a unit of force based on the long ton, traditionally used in the United Kingdom.

• 
  

  A long ton equals 2,240 pounds (lbs).

  
  
• 
  

  The long ton-force is the force exerted by a long ton mass under standard gravity.

  
  
• 
  

  Mathematically:

  
  

• 
  

  It is used in engineering and industries where the long ton is the standard measure of mass.

  
  
• 
  

  This unit is larger than the short ton-force and differs from the metric ton-force.

Piconewton [pN]

Piconewton is a very tiny unit of force in the International System of Units (SI).

• 
  

  1 piconewton (pN) equals $10^{-12}$ newtons (0.000000000001 newton).

  
  
• 
  

  It is commonly used in molecular biology, biophysics, and nanotechnology to measure forces at the molecular or atomic scale.

  
  
• 
  

  To put it in perspective:

  
  

Piconewtons allow scientists to quantify incredibly small forces, such as those involved in DNA stretching or molecular interactions.
