Understanding Pound-Force (lbf) - A Key Unit of Force in Engineering and Physics

The pound-force (lbf) is a unit of force used in the imperial system and United States customary units. It is defined as the force required to accelerate a mass of one pound by one foot per second squared.

One pound-force is equal to 453,592 newtons, which is the force required to accelerate a mass of one kilogram by one meter per second squared.

The pound-force is commonly used in engineering and physics applications where the force required to move an object of a known weight is important. It is also used in aviation and aerospace applications where the weight and thrust of aircraft and rockets are critical factors.
