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.
Gigajoule
A gigajoule (GJ) is a unit of energy equal to one billion joules, used to measure large amounts of energy such as in power generation and fuel consumption.
History/Origin
The gigajoule was introduced as part of the International System of Units (SI) to provide a standard measure for large-scale energy quantities, especially in scientific and industrial contexts, gaining prominence in the 20th century.
Current Use
Gigajoules are commonly used today to quantify energy in fields like energy production, consumption, and engineering, particularly for large-scale systems such as power plants, fuel storage, and energy audits.
