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.

Dyne Centimeter [dyn·cm]

Dyne centimeter (dyn·cm) is a unit of torque or moment of force used in the centimeter-gram-second (CGS) system. It represents the torque produced when a force of one dyne is applied at a distance of one centimeter (cm) from a pivot point. The dyne is a small force unit defined as the force needed to accelerate a mass of one gram at one centimeter per second squared.

This unit is commonly used in fields such as physics, material science, and micro-mechanical engineering, where very small forces and precise torque measurements are necessary. For instance, dyn·cm is useful in calibrating delicate instruments, testing the mechanical properties of small samples, or working with microscale devices.

In SI units, 1 dyn·cm is equivalent to 10⁻⁷ newton-meters (N·m). While SI units like the newton-meter have largely replaced CGS units in most scientific and engineering applications, dyne centimeters remain relevant in specialized areas where the CGS system is still applied for convenience or tradition.
