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.



Kilopound-Force [kipf]


The kilopound-force (kipf) is a unit of force commonly used in engineering, especially in the United States.



  • It equals 1,000 pound-force (lbf).



  • Mathematically:



1 kipf=1,000 lbf≈4,448.22 newtons1 \text{ kipf} = 1,000 \text{ lbf} \approx 4,448.22 \text{ newtons}

  • The kipf is often used to express large forces such as structural loads, stresses in materials, or foundation pressures.



  • It simplifies large force values by grouping them in thousands of pounds-force, making calculations and communication more convenient.
