Femtonewton [fN]

Femtonewton is an ultra-small unit of force in the International System of Units (SI).

• 
  

  1 femtonewton (fN) equals $10^{-15}$ newtons (0.000000000000001 newton).

  
  
• 
  

  It is used in cutting-edge research fields like atomic physics, nanotechnology, and quantum mechanics to measure incredibly tiny forces.

  
  
• 
  

  To put it in perspective:

  
  

Femtonewtons enable precise measurement of forces at atomic and subatomic levels where minute interactions occur.

Pound Foot per Square Second [lbf·ft/s²]

This unit represents a torque or moment of force per unit time squared (though it’s an uncommon combination and can sometimes be context-specific).

• 
  

  It combines pound-force (lbf), a unit of force, with foot (ft), a unit of length, divided by second squared (s²), a unit of time squared.

  
  
• 
  

  It may be used in dynamics or rotational mechanics when dealing with angular accelerations or rate changes of torque.

  
  
• 
  

  In basic terms:

  
  

• 
  

  Since 1 lbf ≈ 4.44822 newtons and 1 ft ≈ 0.3048 meters, this can be converted into SI units as:

  Note: This unit is not commonly standard; usage depends on the specific physical context, like rotational dynamics.
