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/sยฒ).



  • Mathematically:



1 tf=1,000 kgร—9.80665 m/s2=9,806.65 N1 \text{ tf} = 1,000 \text{ kg} \times 9.80665 \text{ m/s}^2 = 9,806.65 \text{ N}

  • 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.


Newton [N]


The newton (N) is the SI unit of force.



  • It is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared.



  • Mathematically:



1 N=1 kgโ‹…m/s21 \text{ N} = 1 \text{ kg} \cdot \text{m/s}^2

  • Named after Sir Isaac Newton for his work on classical mechanics.



  • Commonly used to measure forces such as weight, tension, and thrust in physics and engineering.



Example: The weight of a 1 kg mass under Earth's gravity is approximately 9.8 N.
