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.
Nanowatt
A nanowatt (nW) is a unit of power equal to one billionth of a watt (10^-9 W).
History/Origin
The nanowatt is derived from the SI unit watt, with the prefix 'nano-' indicating a factor of 10^-9. It has been used in scientific and engineering contexts to measure very small power levels, especially in electronics and nanotechnology.
Current Use
Nanowatts are used in fields requiring precise measurement of tiny power quantities, such as in sensor technology, low-power electronics, and nanotechnology research.
