Ounce-Force Inch [ozf·in]

Ounce-force inch (ozf·in) is a unit of torque or moment of force used primarily in industries and applications where very small rotational forces are measured. It represents the torque produced when a force of one ounce-force (ozf) is applied at a distance of one inch (in) from a pivot point. This unit is especially useful in precision engineering, small mechanical assemblies, and electronics, where fine control of torque is necessary.

For example, ounce-force inches are commonly used to specify the torque settings for small screws, delicate instruments, or miniature motors. Since it measures very small torques, ozf·in allows engineers and technicians to ensure components are neither over-tightened nor under-tightened, which could lead to damage or malfunction.

Although the newton-meter (N·m) is the SI unit of torque, and pound-force foot (lbf·ft) is more common in larger mechanical systems, ounce-force inch remains practical in applications requiring detailed precision in the imperial measurement system. To give perspective, 1 ozf·in is approximately 0.007062 N·m.

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.
