Giganewton [GN]


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



  • 1 giganewton (GN) equals 10910^{9} newtons.



  • This unit is used to express very large forces, such as those encountered in heavy engineering projects, large-scale structures, or significant natural forces like earthquakes.



  • To put it in perspective:



1 GN=1,000,000,000 N=109 N1 \text{ GN} = 1,000,000,000 \text{ N} = 10^{9} \text{ N}

Giganewtons help quantify forces far beyond everyday scales but smaller than teranewtons and above.



Poundal [pdl]


The poundal is a unit of force in the foot-pound-second (FPS) system, mainly used in the United States.



  • It is defined as the force required to accelerate a one-pound mass by one foot per second squared.



  • Mathematically:



1 pdl=1 lbร—1 ft/s2=0.138255 newtons1 \text{ pdl} = 1 \text{ lb} \times 1 \text{ ft/s}^2 = 0.138255 \text{ newtons}

  • The poundal is smaller than the pound-force since Earth's gravity accelerates a pound mass at approximately 32.174 ft/sยฒ, making:



1 lbf=32.174 pdl1 \text{ lbf} = 32.174 \text{ pdl}

  • It is mostly of historical interest and rarely used in modern engineering but can appear in classical mechanics problems using the FPS system.
