Ounce-Force Inch

ozf·in

Definition

The ounce-force inch (ozf·in) is an imperial unit of torque, equal to 0.007061552 newton meters. It represents the rotational force produced by one ounce-force applied at one inch from the pivot point.

History/Origin

This unit was commonly used in the US customary system for small-scale torque measurements in precision engineering and manufacturing. It provided a practical unit for inch-scale applications.

Current Use

Frequently used in precision manufacturing, small mechanical devices, and laboratory equipment where inch-scale measurements and ounce-force applications are standard in US engineering practice.

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.
