Ounce-Force [ozf]


Ounce-force (ozf) is a unit of force used mainly in the Imperial and US customary systems.



  • It represents the force exerted by gravity on a mass of one ounce (oz) under standard Earth gravity.



  • Since there are 16 ounces in a pound-force, mathematically:



1 ozf=116 lbf0.278 newtons1 \text{ ozf} = \frac{1}{16} \text{ lbf} \approx 0.278 \text{ newtons}

  • Ounce-force is typically used for measuring small forces in applications like mechanical devices, small-scale forces, or packaging.



  • It provides a convenient way to express forces smaller than a pound-force in everyday and engineering contexts.




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.
