Gram-Force Millimeter

gf·mm

Definition

The gram-force millimeter (gf·mm) is a gravitational metric unit of torque, equal to 9.80665E-6 newton meters. It represents the rotational force produced by one gram-force applied at one millimeter from the pivot point.

History/Origin

This unit was used in the technical system of units for very precise torque measurements at millimeter scales. It provided a practical unit for micro-mechanical applications and precision assembly work.

Current Use

Rarely used in modern applications, but may be encountered in specialized scientific research or historical technical specifications where very precise small-scale measurements are required.
