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.
Microwatt
A microwatt (µW) is a unit of power equal to one millionth of a watt, used to measure very small amounts of power.
History/Origin
The microwatt was introduced as part of the metric system's effort to provide standardized units for small quantities of power, especially in scientific and technological contexts, gaining prominence with the adoption of the International System of Units (SI).
Current Use
Microwatts are used in fields such as electronics, telecommunications, and biomedical engineering to quantify low power levels in devices, sensors, and circuits.
