Picowatt
A picowatt (pW) is a unit of power equal to one trillionth (10^-12) of a watt.
History/Origin
The picowatt was introduced as part of the SI prefixes to measure extremely small amounts of power, especially in scientific and technological contexts, following the standardization of the watt as the SI unit of power.
Current Use
Picowatts are used in fields such as electronics, physics, and biology to quantify very low power levels, including in sensor measurements, quantum physics, and nanotechnology applications.
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.
