Ton-Force (Metric) [tf]

Ton-force (metric), also called tonne-force or metric ton-force (tf), is a unit of force based on the force exerted by one metric ton (1,000 kilograms) under standard gravity.

• 
  

  Defined as the force exerted by a mass of 1 metric ton under Earth's gravity (9.80665 m/s²).

  
  
• 
  

  Mathematically:

  
  

• 
  

  Though not an SI unit, it is widely used in engineering and heavy industries to measure large forces.

  
  

Example: A force of 5 tf corresponds to approximately 49,033 newtons.

Millinewton [mN]

Millinewton is a small unit of force in the International System of Units (SI).

• 
  

  1 millinewton (mN) equals $10^{-3}$ newtons (0.001 newton).

  
  
• 
  

  It is commonly used to measure very small forces, such as in microengineering, delicate instrumentation, or biomechanical applications.

  
  
• 
  

  To put it in perspective:

  
  

Millinewtons are useful for expressing forces smaller than centinewtons, allowing precise measurement of low-force phenomena.
