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/s24.44822 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.



Joule per Centimeter [J/cm]


Joule per centimeter is a unit of energy per unit length.



  • It measures how much energy is distributed or transferred over each centimeter.



  • Since 1 centimeter = 0.01 meter, joule per centimeter is related to joule per meter by:



1 J/cm=100 J/m1 \text{ J/cm} = 100 \text{ J/m}

  • Like joule per meter, this unit is used to describe energy density along a line, such as tension in a wire or energy stored per unit length in materials.



  • Also, it can relate to force, since:



1 J/m=1 N    1 J/cm=100 N1 \text{ J/m} = 1 \text{ N} \implies 1 \text{ J/cm} = 100 \text{ N}

Thus, joule per centimeter expresses a larger force equivalent compared to joule per meter.
