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Today, the poundal is largely obsolete and rarely used, having been replaced by the SI unit newton; however, it may still be referenced in historical contexts or specialized engineering fields.
Pound-Force
Pound-force (lbf) is a unit of force in the imperial system, defined as the force required to accelerate a one-pound mass at a rate of 32.174 feet per second squared.
History/Origin
The pound-force originated from the British Imperial system and has been used historically in engineering and physics to quantify force, especially in the United States and the UK, before the widespread adoption of the SI system.
Current Use
Today, pound-force is primarily used in the United States and some other countries for engineering, manufacturing, and mechanical applications where imperial units are still prevalent, often in contexts like specifying engine torque or structural loads.
