Gram-Force Meter [gf·m]

Gram-force meter (gf·m) is a unit of torque or moment of force that measures the rotational force produced when a force of one gram-force (gf) is applied at a distance of one meter (m) from a pivot point. This unit is often used in mechanical engineering, precision instrumentation, and scientific research where moderately small torque values need to be measured or specified.

Although the newton-meter (N·m) is the SI standard unit of torque, the gram-force meter is still useful in certain contexts, particularly when forces are expressed in gram-force due to traditional or practical reasons. The gf·m allows for torque measurements in applications involving moderate force levels but requiring a metric unit of length that is larger than centimeters or millimeters.

To put it in perspective, 1 gf·m equals approximately 9.80665 × 10⁻³ newton-meters. This unit can be handy in calibrating instruments or testing devices that operate within low to medium torque ranges, bridging the gap between small-scale and larger-scale torque measurements.

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.
