Gram-Force Millimeter [gf·mm]

Gram-force millimeter (gf·mm) is a unit of torque or moment of force used to measure very small rotational forces, typically in delicate mechanical systems or precision instruments. It represents the torque produced when a force of one gram-force (gf) is applied at a distance of one millimeter (mm) from a pivot point.

This unit is particularly useful in fields such as microengineering, watchmaking, electronics, and small-scale mechanical testing, where tiny torques need to be accurately measured and controlled. For example, gf·mm is often used to specify the torque for miniature screws or the resistance of small mechanical components.

Although the newton-meter (N·m) is the standard SI unit for torque, gf·mm offers a practical scale for extremely low torque measurements, providing precision that is more intuitive when dealing with tiny forces and distances. To convert, 1 gf·mm is approximately 9.80665 × 10⁻⁶ N·m.

Using gram-force millimeters allows engineers and technicians to ensure proper functioning of small devices by preventing over-tightening or insufficient torque application.

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.
