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.

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.
