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.



Joule per Centimeter [J/cm]


Joule per centimeter is a unit of energy per unit length.



  • It measures how much energy is distributed or transferred over each centimeter.



  • Since 1 centimeter = 0.01 meter, joule per centimeter is related to joule per meter by:



1 J/cm=100 J/m1 \text{ J/cm} = 100 \text{ J/m}

  • Like joule per meter, this unit is used to describe energy density along a line, such as tension in a wire or energy stored per unit length in materials.



  • Also, it can relate to force, since:



1 J/m=1 N    1 J/cm=100 N1 \text{ J/m} = 1 \text{ N} \implies 1 \text{ J/cm} = 100 \text{ N}

Thus, joule per centimeter expresses a larger force equivalent compared to joule per meter.
