Pound-Force [lbf]


Pound-force (lbf) is a unit of force commonly used in the United States and some other countries using the Imperial system.



  • It is defined as the force exerted by gravity on a mass of one pound (lb) under standard Earth gravity.



  • Mathematically:



1 lbf=1 lb×9.80665 m/s2≈4.44822 newtons1 \text{ lbf} = 1 \text{ lb} \times 9.80665 \text{ m/s}^2 \approx 4.44822 \text{ newtons}

  • Pound-force is widely used in engineering, mechanics, and everyday contexts in countries that use Imperial or US customary units.



  • It measures force similarly to how newtons do in the metric system but based on pounds instead of kilograms.



Dyne [dyn]


The dyne is a unit of force in the centimeter-gram-second (CGS) system of units.



  • Defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared.



  • Mathematically:



1 dyn=1 g×1 cm/s2=10−5 newtons1 \text{ dyn} = 1 \text{ g} \times 1 \text{ cm/s}^2 = 10^{-5} \text{ newtons}

  • The dyne is much smaller than the newton and is used primarily in physics and engineering fields that use the CGS system.



  • For comparison:



1 N=105 dyn1 \text{ N} = 10^{5} \text{ dyn}

Dyne is often used in fields like material science, mechanics, and electromagnetism when dealing with small forces.
