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Today, the poundal is largely obsolete and rarely used, having been replaced by the SI unit newton; however, it may still be referenced in historical contexts or specialized engineering fields.
Kilogram-Force
Kilogram-force (kgf) is a unit of force defined as the force exerted by one kilogram of mass in standard gravity, approximately equal to 9.80665 newtons.
History/Origin
The kilogram-force was historically used in engineering and physics to express forces in terms of the mass unit kilogram and the acceleration due to gravity. It was more common before the widespread adoption of the newton as the standard SI unit of force.
Current Use
Kilogram-force is largely obsolete in scientific contexts and has been replaced by the newton in the International System of Units (SI). However, it may still be encountered in certain engineering fields or older documentation, especially in regions or industries that use customary units.
