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.

Pound foot/square second
lb⋅ft/s²
Definition
Pound foot per square second is a unit of force in the foot-pound-second (FPS) system of units. It is defined as the force required to accelerate a mass of one pound at a rate of one foot per second squared. This unit is equivalent to one poundal.
History/Origin
Pound foot per square second was introduced as part of the FPS (foot-pound-second) system of units in the 19th century. It was widely used in physics and engineering before the adoption of the MKS (meter-kilogram-second) system. The unit represents the fundamental relationship between mass, acceleration, and force.
Current Use
Still used in some areas of physics and engineering, particularly in the United States. Common in some engineering applications where the FPS system is still used. Used in some scientific instruments and laboratory equipment that were designed using the FPS system.
