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.



Dyne [dyn]


The dyne is a unit of force in the centimeter-gram-second (CGS) system of units.



  • Defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared.



  • Mathematically:



1 dyn=1 g×1 cm/s2=105 newtons1 \text{ dyn} = 1 \text{ g} \times 1 \text{ cm/s}^2 = 10^{-5} \text{ newtons}

  • The dyne is much smaller than the newton and is used primarily in physics and engineering fields that use the CGS system.



  • For comparison:



1 N=105 dyn1 \text{ N} = 10^{5} \text{ dyn}

Dyne is often used in fields like material science, mechanics, and electromagnetism when dealing with small forces.
