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.
Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
