Kilonewton [kN]

The kilonewton (kN) is a unit of force in the International System of Units (SI).

• 
  

  1 kilonewton equals 1,000 newtons:

  
  

• 
  

  It represents the force required to accelerate a 1,000 kg mass at 1 meter per second squared.

  
  
• 
  

  Kilonewtons are commonly used to measure larger forces in engineering, construction, and physics, such as the load on structures, thrust in engines, or tension in cables.

  
  

Example: The force exerted by a 100 kg mass under Earth's gravity is approximately 0.98 kN.

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.
