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.




Pond [p]


The pond is a historical unit of force, equivalent to the force exerted by gravity on a mass of one gram.



  • It is part of the gram-force system and was widely used before the adoption of the newton in the SI system.



  • Mathematically:



1 pond=1 gram×9.80665 m/s2=0.00980665 newtons1 \text{ pond} = 1 \text{ gram} \times 9.80665 \text{ m/s}^2 = 0.00980665 \text{ newtons}

  • In other words, 1 pond is approximately 0.00981 newtons.



  • The pond is rarely used today, having been replaced by the newton, but it may still appear in older scientific literature or certain niche applications.



  • It is similar in concept to the gram-force (gf).
