Pound Foot per Square Second [lbf·ft/s²]


This unit represents a torque or moment of force per unit time squared (though it’s an uncommon combination and can sometimes be context-specific).



  • It combines pound-force (lbf), a unit of force, with foot (ft), a unit of length, divided by second squared (s²), a unit of time squared.



  • It may be used in dynamics or rotational mechanics when dealing with angular accelerations or rate changes of torque.



  • In basic terms:



1 lbf\cdotpft/s2=force×distance÷time21 \text{ lbf·ft/s}^2 = \text{force} \times \text{distance} \div \text{time}^2

  • Since 1 lbf ≈ 4.44822 newtons and 1 ft ≈ 0.3048 meters, this can be converted into SI units as:



1 lbf\cdotpft/s21.35582 N\cdotpm/s21 \text{ lbf·ft/s}^2 \approx 1.35582 \text{ N·m/s}^2

  • Note: This unit is not commonly standard; usage depends on the specific physical context, like rotational dynamics.




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.
