Newton Millimeter
N·mm
Definition
The newton millimeter (N·mm) is a metric unit of torque, equal to 0.001 newton meters. It represents the rotational force produced when a force of one newton is applied perpendicularly at a distance of one millimeter from the pivot point.
History/Origin
This unit was developed as a submultiple of the newton meter for very precise torque measurements. It became important in precision engineering and manufacturing where millimeter-scale measurements are standard.
Current Use
Commonly used in precision manufacturing, micro-mechanics, and laboratory instruments where very small torque values need to be measured accurately. It is essential for fine mechanical adjustments and precision assembly work.

Pound-Force Inch
lbf·in
Definition
The pound-force inch (lbf·in) is an imperial unit of torque, equal to 0.1129848333 newton meters. It represents the rotational force produced by one pound-force applied at one inch from the pivot point.
History/Origin
This unit was commonly used in the US customary system for smaller torque measurements in precision engineering and manufacturing. It provided a practical unit for inch-scale applications in mechanical design.
Current Use
Widely used in precision manufacturing, small mechanical devices, and laboratory equipment where inch-scale measurements and pound-force applications are standard in US engineering practice.
