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.

Kilogram-Force Millimeter [kgf·mm]

Kilogram-force millimeter (kgf·mm) is a unit of torque or moment of force used to quantify small rotational forces where the force is expressed in kilogram-force (kgf) and the distance in millimeters (mm). It represents the torque generated when a force of one kilogram-force is applied at a lever arm length of one millimeter from the pivot point.

This unit is commonly employed in fields such as mechanical engineering, precision instrument calibration, and small machinery design. It is especially useful for measuring or specifying torque in devices requiring fine control over small rotational forces, such as torque on small bolts, delicate mechanical assemblies, or calibration of torque wrenches.

While the standard SI unit for torque is the newton-meter (N·m), kgf·mm provides a convenient scale in applications where the metric system is preferred but the force is expressed in kilogram-force due to historical or practical reasons. For reference, 1 kgf·mm is approximately equal to 9.80665 × 10⁻³ newton-meters.

Using kilogram-force millimeters allows for precise torque measurement in contexts where small-scale torque values are critical to ensure proper assembly and operation of mechanical systems.
