Pound-Force Foot
The pound-force foot (lbf·ft) is a unit of torque or moment of force, representing the force of one pound-force applied at a perpendicular distance of one foot from the pivot point.
History/Origin
The pound-force foot originated from the Imperial system of units, primarily used in the United States, to quantify torque in mechanical and engineering contexts before the widespread adoption of the SI system.
Current Use
Today, the pound-force foot is still used in certain engineering fields, particularly in the United States, to measure torque in automotive, mechanical, and structural applications, although the SI unit newton meter 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.
