Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
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.
