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.

Dyne Centimeter [dyn·cm]

Dyne centimeter (dyn·cm) is a unit of torque or moment of force used in the centimeter-gram-second (CGS) system. It represents the torque produced when a force of one dyne is applied at a distance of one centimeter (cm) from a pivot point. The dyne is a small force unit defined as the force needed to accelerate a mass of one gram at one centimeter per second squared.

This unit is commonly used in fields such as physics, material science, and micro-mechanical engineering, where very small forces and precise torque measurements are necessary. For instance, dyn·cm is useful in calibrating delicate instruments, testing the mechanical properties of small samples, or working with microscale devices.

In SI units, 1 dyn·cm is equivalent to 10⁻⁷ newton-meters (N·m). While SI units like the newton-meter have largely replaced CGS units in most scientific and engineering applications, dyne centimeters remain relevant in specialized areas where the CGS system is still applied for convenience or tradition.
