Pound-Force Inch
Pound-force inch (lbf·in) is a unit of torque representing the torque resulting from a one-pound-force applied at a perpendicular distance of one inch from the pivot point.
History/Origin
The pound-force inch has been used historically in engineering and mechanical contexts to quantify torque, especially in the United States, based on the imperial system of units. It originated from the need to measure rotational force in machinery and automotive applications.
Current Use
Today, pound-force inch is still used in engineering, automotive, and mechanical fields to specify torque values, particularly in the United States. It is often converted to SI units like newton-meters for international standardization.
Foot-Pound
A foot-pound is a unit of energy or work equal to the work done when a force of one pound-force is exerted over a distance of one foot.
History/Origin
The foot-pound has been used primarily in the United States and the United Kingdom as a customary unit of energy, originating from imperial and US customary measurement systems, before the widespread adoption of the SI system.
Current Use
Today, the foot-pound is still used in certain fields such as engineering, automotive, and aerospace industries in the US for expressing torque and energy, although the SI unit joule is more common internationally.
