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.

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.
