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.
Watt-Second
A watt-second (W·s) is a unit of energy equivalent to one joule, representing the amount of energy transferred or converted when one watt of power is applied for one second.
History/Origin
The watt-second originated from the SI system of units, where the watt (W) is the SI derived unit of power, and the second (s) is the SI base unit of time. It has been used historically in physics and engineering to quantify energy, especially in contexts where energy transfer occurs over short durations.
Current Use
The watt-second is primarily used in scientific and engineering contexts to measure small amounts of energy, such as in electrical and mechanical systems. It is often replaced by the joule in modern applications but remains a recognized unit within the energy converter category.
