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.

Dyne Millimeter [dyn·mm]

Dyne millimeter (dyn·mm) is a unit of torque or moment of force in the centimeter-gram-second (CGS) system of units. It measures the torque produced when a force of one dyne is applied at a distance of one millimeter (mm) from a pivot point. The dyne is a small unit of force, defined as the force required to accelerate a mass of one gram at a rate of one centimeter per second squared.

This unit is commonly used in physics, materials science, and engineering, especially in studies involving very small forces and precise torque measurements such as in micro-mechanics, thin film testing, and small-scale instrument calibration. Because both the dyne and the millimeter are small units, dyn·mm is ideal for quantifying extremely low torques that would be impractical to express in larger units like newton-meters.

In terms of SI units, 1 dyn·mm equals 10⁻⁸ newton-meters (N·m). Despite the predominance of SI units in modern science and engineering, the dyne millimeter remains useful in certain specialized contexts where the CGS system is still preferred for historical reasons or practical convenience.
