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 lb×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/s², 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.


Meganewton [MN]


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



  • 1 meganewton (MN) equals 10610^{6} newtons (1,000,000 newtons).



  • It is commonly used to measure very large forces in engineering, such as the thrust of rocket engines or loads on large structures.



  • To give perspective:



1 MN=1,000,000 N=106 N1 \text{ MN} = 1,000,000 \text{ N} = 10^{6} \text{ N}

Meganewtons are useful for quantifying forces much greater than those in everyday life but smaller than giganewtons and above.
