Attowatt
An attowatt (aW) is a unit of power equal to 10^-18 watts, representing an extremely small amount of power.
History/Origin
The attowatt is part of the SI prefix system introduced to denote very small quantities, with 'atto-' representing 10^-18. It has been used mainly in scientific contexts to measure minuscule power levels.
Current Use
The attowatt is rarely used in practical applications but may be referenced in scientific research involving extremely low power measurements, such as in quantum physics or nanotechnology.
Btu (Th)/second
Btu (th)/second is a unit of power representing the rate of energy transfer, specifically one British thermal unit (th) per second.
History/Origin
The British thermal unit (th) has been used historically in the United States for measuring heat energy, and its use in power units like Btu (th)/s dates back to traditional energy and heat transfer calculations in engineering and thermodynamics.
Current Use
Btu (th)/second is primarily used in the United States for industrial and engineering applications involving heat transfer rates, although it is less common compared to SI units like watts.
