Inch [lbf·in]


Pound-force inch, abbreviated as lbf·in, is a unit of torque in the Imperial system. It measures the rotational force applied at a distance of one inch from a pivot point. Torque represents the tendency of a force to rotate an object about an axis, and lbf·in is commonly used in mechanical engineering, automotive applications, and machinery design to quantify small to medium torque values. One lbf·in corresponds to applying a force of one pound-force at a perpendicular distance of one inch from the rotation axis. For example, tightening a bolt with a torque wrench set to 50 lbf·in means applying a force that produces 50 pound-force inches of rotational effort. This unit is particularly useful for fasteners, small motors, and mechanical assemblies where precise torque is crucial to prevent over-tightening or under-tightening. While larger torque values are often measured in pound-force feet (lbf·ft) or Newton-meters (N·m), lbf·in provides a convenient scale for tasks requiring finer control. Understanding lbf·in ensures safe and effective mechanical operation, proper assembly of components, and accurate measurement of rotational forces in engineering and industrial applications.


Ounce-Force Foot [ozf·ft]


Ounce-force foot (ozf·ft) is a unit of torque or moment of force used to measure rotational force in situations requiring finer precision than pound-force foot (lbf·ft) but larger than ounce-force inch (ozf·in). It represents the torque generated when a force of one ounce-force (ozf) is applied at a distance of one foot (ft) from a pivot point. This unit is particularly useful in mechanical engineering, instrumentation, and small-scale mechanical systems where moderate torques are involved.


Ounce-force foot is valuable for quantifying torque in applications such as small machinery, instrument calibration, or assembly of mechanical devices where precise control of rotational force is critical. It helps ensure components are tightened or adjusted correctly without causing damage or failure.


While the newton-meter (N·m) is the SI unit for torque and the pound-force foot (lbf·ft) is common for larger forces, the ounce-force foot unit fits niche applications that require intermediate torque measurements within the imperial system. For reference, 1 ozf·ft equals approximately 0.00885 newton-meters.
