Btu (It)/minute
Btu (IT)/minute is a unit of power representing the rate of energy transfer, specifically in British thermal units per minute.
History/Origin
The British thermal unit (Btu) has been used historically in the United States and the UK to measure heat energy. The 'IT' designation refers to the International Table value of the Btu. The unit per minute was adopted to quantify power, which is energy transfer rate, in various engineering and thermodynamic contexts.
Current Use
Btu (IT)/minute is used in engineering, HVAC, and thermodynamics to measure heat transfer rates, especially in systems where energy flow is expressed per unit time. It is part of power conversions within the broader category of common energy and power units.
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.
