Gram-Force [gf]


The gram-force (gf) is a unit of force based on the force exerted by one gram of mass under standard gravity.



  • It is defined as the force exerted by a mass of 1 gram under the acceleration due to gravity (9.80665 m/s²).



  • Mathematically:



1 gf=1 g×9.80665 m/s2=9.80665×103 N=0.00980665 N1 \text{ gf} = 1 \text{ g} \times 9.80665 \text{ m/s}^2 = 9.80665 \times 10^{-3} \text{ N} = 0.00980665 \text{ N}

  • Although not an SI unit, gram-force is used in some fields like engineering and material science for small force measurements.



Example: The force due to a 500 g mass is 500 gf, which is approximately 4.9 newtons.



Centinewton [cN]


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



  • 1 centinewton (cN) equals 10210^{-2} newtons (0.01 newton).



  • It is used to measure very small forces, useful in precision engineering, material testing, and small-scale physics experiments.



  • To put it in perspective:



1 cN=0.01 N1 \text{ cN} = 0.01 \text{ N}

Centinewtons allow convenient expression of forces smaller than decinewtons but larger than millinewtons.
