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.
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.
