Pound-Force Foot [lbf·ft]

Pound-force foot (lbf·ft) is a unit of torque that measures the rotational force applied when a force of one pound-force is exerted perpendicularly at a distance of one foot from the axis of rotation. One pound-force represents the force exerted by a mass of one pound under standard gravity. This unit is commonly used in mechanical engineering, automotive design, construction, and industrial applications to evaluate torque, rotational performance, and mechanical efficiency. A higher lbf·ft value indicates greater torque and stronger rotational force, while a lower value signifies less force applied. Engineers and designers use this measure to calculate torque requirements, design engines, gear systems, and machinery, and ensure stability and safety in rotating components. By linking force and distance from the rotation axis, pound-force foot provides a practical and widely used unit for analyzing and managing rotational dynamics in mechanical, industrial, and engineering applications.

Poundal Inch [pdl·in]

Poundal inch (pdl·in) is a unit of torque that measures the rotational force produced when one poundal of force is applied perpendicularly at a distance of one inch from the axis of rotation. A poundal is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at one foot per second squared. Poundal inch is particularly useful for small-scale mechanical systems, precision engineering, and educational applications where forces and torques are relatively low and distances are short. A higher pdl·in value indicates greater torque and more resistance to rotation, while a lower value means the object rotates more easily. Engineers and students use this unit to calculate torque, angular acceleration, and energy in miniature machinery, experimental setups, or theoretical problems. By linking force and rotational distance in inches, poundal inch provides a practical and precise measure for understanding and managing rotational dynamics in compact or small-scale mechanical systems.
