Kilogram-Force Millimeter [kgf·mm]

Kilogram-force millimeter (kgf·mm) is a unit of torque or moment of force used to quantify small rotational forces where the force is expressed in kilogram-force (kgf) and the distance in millimeters (mm). It represents the torque generated when a force of one kilogram-force is applied at a lever arm length of one millimeter from the pivot point.

This unit is commonly employed in fields such as mechanical engineering, precision instrument calibration, and small machinery design. It is especially useful for measuring or specifying torque in devices requiring fine control over small rotational forces, such as torque on small bolts, delicate mechanical assemblies, or calibration of torque wrenches.

While the standard SI unit for torque is the newton-meter (N·m), kgf·mm provides a convenient scale in applications where the metric system is preferred but the force is expressed in kilogram-force due to historical or practical reasons. For reference, 1 kgf·mm is approximately equal to 9.80665 × 10⁻³ newton-meters.

Using kilogram-force millimeters allows for precise torque measurement in contexts where small-scale torque values are critical to ensure proper assembly and operation of mechanical systems.

Newton Centimeter [N·cm]

Newton centimeter (N·cm) 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 centimeter from the axis of rotation. It is particularly useful for small-scale or precision applications where forces are relatively low and distances are short, such as in electronics, robotics, watchmaking, and laboratory experiments. A higher N·cm value indicates stronger torque and greater resistance to rotational motion, while a lower value signifies less force and easier rotation. Engineers and designers use this unit to calculate torque, angular acceleration, and energy requirements for small mechanical components like gears, motors, and sensors. By combining force and a short rotational distance, newton centimeter provides a practical and precise measure for analyzing and managing torque in compact or delicate systems, ensuring accuracy, efficiency, and stability in micro-scale mechanical and engineering applications.
