Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics in the United States before the widespread adoption of the SI system.
Current Use
Today, the poundal is largely obsolete and rarely used, having been replaced by the SI unit newton; however, it may still be referenced in historical contexts or specialized engineering fields.
Petanewton
A petanewton (PT) is a unit of force equal to 10^15 newtons, used for measuring extremely large forces.
History/Origin
The petanewton was introduced as part of the SI prefixes to facilitate the expression of very large forces, although it is rarely used in practical applications due to the scale of forces involved.
Current Use
The petanewton is primarily used in scientific contexts involving large-scale forces, such as astrophysics and cosmology, but remains a theoretical unit with limited practical application.
