Gram-Force Meter [gf·m]

Gram-force meter (gf·m) is a unit of torque or moment of force that measures the rotational force produced when a force of one gram-force (gf) is applied at a distance of one meter (m) from a pivot point. This unit is often used in mechanical engineering, precision instrumentation, and scientific research where moderately small torque values need to be measured or specified.

Although the newton-meter (N·m) is the SI standard unit of torque, the gram-force meter is still useful in certain contexts, particularly when forces are expressed in gram-force due to traditional or practical reasons. The gf·m allows for torque measurements in applications involving moderate force levels but requiring a metric unit of length that is larger than centimeters or millimeters.

To put it in perspective, 1 gf·m equals approximately 9.80665 × 10⁻³ newton-meters. This unit can be handy in calibrating instruments or testing devices that operate within low to medium torque ranges, bridging the gap between small-scale and larger-scale torque measurements.

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.
