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.

Gram-Force Centimeter [gf·cm]

Gram-force centimeter (gf·cm) is a unit of torque or moment of force used to measure small rotational forces, commonly applied in precision engineering, watchmaking, electronics, and small mechanical assemblies. It represents the torque generated when a force of one gram-force (gf) is applied at a distance of one centimeter (cm) from a pivot point.

This unit is especially useful for situations requiring accurate control of low-level torque, such as tightening tiny screws, calibrating sensitive instruments, or testing miniature mechanical components. The gram-force centimeter provides a practical and intuitive scale for these tasks, bridging the gap between very fine torque measurements and larger units like pound-force foot or newton-meter.

Although the SI unit of torque is the newton-meter (N·m), the gf·cm remains valuable in applications where imperial or metric small-force units are more convenient. To convert, 1 gf·cm is approximately 9.80665 × 10⁻⁵ N·m.

Using gram-force centimeters helps ensure the precision and reliability of devices by preventing damage due to improper torque application, making it a favored unit in many delicate engineering fields.
