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.
Btu (Th)/hour
Btu (th)/hour is a unit of power that measures the rate of energy transfer, specifically the amount of thermal energy in British thermal units (Btu) delivered or consumed per hour.
History/Origin
The Btu (th)/hour originated from the British thermal unit (Btu), a traditional unit of heat energy, and has been used primarily in the heating and energy industries to quantify thermal power rates. Its usage dates back to the early 20th century as a standard measure in thermal energy calculations.
Current Use
Today, Btu (th)/hour is used mainly in the heating, ventilation, and air conditioning (HVAC) industry, as well as in energy consumption and efficiency assessments, to specify thermal power rates of equipment and systems.
