Newton Meter [N·m]

Newton meter (N·m) is the standard SI unit of torque, measuring the rotational force applied to an object around an axis. It combines force in newtons (N) with distance in meters (m) from the axis of rotation. One newton meter represents the torque generated when a force of one newton is applied perpendicularly at a distance of one meter from the rotation axis. This unit is widely used in physics, mechanical engineering, automotive design, robotics, and industrial applications to quantify torque, rotational performance, and mechanical efficiency. A higher N·m value indicates stronger torque and greater ability to cause angular acceleration, while a lower value signifies less rotational force. Engineers and designers use this measure to calculate torque requirements, optimize machinery, ensure component stability, and prevent mechanical failure. By linking force and rotational distance, newton meter provides a practical, precise, and universally recognized standard for analyzing and managing torque in a variety of mechanical, industrial, and scientific applications.

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.
