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.

Newton Millimeter [N·mm]

Newton millimeter (N·mm) is a unit of torque that measures the rotational force applied when a force of one newton is exerted perpendicularly at a distance of one millimeter from the axis of rotation. It is especially useful for very small-scale or high-precision applications, such as micro-mechanical systems, electronics, robotics, and laboratory instruments, where tiny forces need accurate measurement. A higher N·mm value indicates greater torque and more resistance to rotation, while a lower value represents less rotational force and easier motion. Engineers, designers, and researchers use this unit to calculate torque, angular acceleration, and energy requirements for miniature components like micro-gears, motors, sensors, and precision instruments. By combining force with very small rotational distances, newton millimeter provides a practical and precise measure for managing and analyzing torque in compact or highly sensitive mechanical systems, ensuring accuracy, efficiency, and stability in delicate applications.
