Kilogram-Force [kgf]


Kilogram-force (kgf) is a unit of force based on the force exerted by one kilogram of mass under standard gravity.



  • It is defined as the force exerted by a mass of 1 kilogram under Earth's gravitational acceleration (9.80665 m/s²).



  • Mathematically:



1 kgf=1 kg×9.80665 m/s2=9.80665 N1 \text{ kgf} = 1 \text{ kg} \times 9.80665 \text{ m/s}^2 = 9.80665 \text{ N}

  • Although not an SI unit, kilogram-force is commonly used in engineering and industries to express force more intuitively related to mass.



Example: A force of 10 kgf corresponds to approximately 98.07 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 kgm/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.
