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.

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.
