Kilogram-Force Centimeter [kgf·cm]

Kilogram-force centimeter (kgf·cm) is a unit of torque or moment of force that measures rotational force by applying a force of one kilogram-force (kgf) at a distance of one centimeter (cm) from a pivot point. This unit is widely used in mechanical engineering, instrument calibration, and small machinery design, where moderate torque values need to be measured with precision.

The kilogram-force (kgf) itself is a unit of force based on the gravitational force exerted by one kilogram of mass, making kgf·cm intuitive for practical applications involving mechanical components and assemblies. It is especially common in industries dealing with small to medium-sized torques, such as automotive, robotics, and manufacturing sectors.

Though the newton-meter (N·m) is the official SI unit of torque, kgf·cm remains popular in many settings due to historical use and convenience when working with forces in kilograms and distances in centimeters. For conversion, 1 kgf·cm is approximately 0.09807 newton-meters.

Using kilogram-force centimeters helps engineers and technicians accurately control and specify torque levels, preventing damage and ensuring optimal performance of mechanical systems.

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.
