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.
Millijoule
A millijoule (mJ) is a unit of energy equal to one thousandth of a joule, where 1 joule equals 1 newton meter or 1 kg·m²/s².
History/Origin
The millijoule is derived from the SI base unit joule, with the prefix 'milli' indicating a factor of 10⁻³. It has been used in scientific and engineering contexts to measure small amounts of energy, especially in fields like electronics and biomechanics.
Current Use
The millijoule is commonly used today to quantify small energy quantities in electronics, biomedical applications, and energy measurements where precision at a small scale is required.
