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.
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.
