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 \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.

Petanewton [PN]

Petanewton is a very large unit of force in the International System of Units (SI).

1 petanewton (PN) equals $10^{15}$ newtons.
It represents forces much larger than those encountered in everyday life or typical engineering but smaller than exanewtons.
Such forces might be relevant in astrophysics, like the force between massive celestial bodies.
