Attonewton [aN]


Attonewton is an extraordinarily small unit of force in the International System of Units (SI).



  • 1 attonewton (aN) equals 101810^{-18} newtons (0.000000000000000001 newton).



  • It is used in highly specialized fields such as quantum physics, nanotechnology, and advanced experimental research where forces are incredibly minute.



  • To put it in perspective:



1 aN=0.000000000000000001 N1 \text{ aN} = 0.000000000000000001 \text{ N}

Attonewtons allow scientists to quantify forces at the tiniest scales imaginable, beyond typical atomic interactions.


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.
