Pound-force
lbf
Definition
Pound-force represents the gravitational force exerted on a mass of one pound under standard gravity conditions. It equals approximately 4.45 Newtons and is commonly used in engineering applications, particularly in the United States and other countries using imperial units.
History/Origin
Pound-force was widely used in engineering before the Newton became the standard SI unit. It provided an intuitive way to express forces in terms of familiar mass units. The unit was particularly popular in US engineering practices and remains in use in many applications.
Current Use
Still widely used in engineering applications, particularly in the United States. Common in mechanical engineering for torque specifications and in automotive applications. Used in material testing and in many industrial processes where the relationship to mass is important.

Petanewton
PT
Definition
A petanewton equals 10^15 Newtons and represents an extremely large force unit used in theoretical physics and astrophysics. This unit is employed for describing forces on astronomical scales and in high-energy physics applications.
History/Origin
The petanewton was established as part of the metric system's decimal prefix system. The prefix "peta" (meaning 10^15) was adopted in 1975. This unit is used primarily in theoretical physics and astrophysical calculations involving massive forces.
Current Use
Used in theoretical physics and astrophysics for describing extremely large forces. Applied in calculations involving massive celestial objects, galactic interactions, and high-energy physics experiments. Primarily a theoretical unit for scientific research.
