Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
Pound-Foot/second
A pound-foot per second (lbf·ft/s) is a unit of power representing the rate at which work is done or energy is transferred, equivalent to one pound-force acting through a distance of one foot per second.
History/Origin
The pound-foot per second has been used primarily in engineering contexts within the Imperial system to quantify power, especially in mechanical and automotive applications, though it is less common than other units like horsepower.
Current Use
Today, the pound-foot per second is rarely used; it is mainly referenced in historical data or specific engineering calculations involving Imperial units, with the more standard unit of power being the horsepower or the watt in SI units.
