Hectonewton [hN]


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



  • 1 hectonewton (hN) equals 10210^{2} newtons (100 newtons).



  • It is used to measure moderate forces, such as those encountered in mechanical engineering or smaller-scale industrial applications.



  • To put it into perspective:



1 hN=100 N1 \text{ hN} = 100 \text{ N}

Hectonewtons provide a convenient way to express forces larger than newtons but smaller than kilonewtons.



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.
