Kilojoule
A kilojoule (kJ) is a unit of energy equal to 1,000 joules, used to quantify energy transfer or work done.
History/Origin
The kilojoule was introduced as part of the International System of Units (SI) to provide a convenient scale for measuring energy, especially in fields like nutrition and physics, replacing the joule for larger quantities.
Current Use
The kilojoule is widely used in nutrition to express food energy content, in physics and engineering to measure energy transfer, and in various scientific and industrial applications within the 'Energy' converter category.
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.
