Key Terminology
-
Ounce-force inch [ozf·in]
-
A torque unit representing one ounce-force applied at a perpendicular distance of one inch from the pivot, used for very small moments.
-
Kilogram-force millimeter [kgf·mm]
-
A torque unit defined by the moment from a force of one kilogram-force applied at a perpendicular distance of one millimeter.
-
Torque
-
A measure of the turning force applied to an object, often expressed in units combining force and distance.
