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.
Petawatt
A petawatt (PW) is a unit of power equal to 10^15 watts, used to measure extremely high power levels.
History/Origin
The petawatt was introduced in the 1980s as part of the SI prefixes to describe ultra-high power outputs, particularly in laser physics and astrophysics research.
Current Use
Petawatts are primarily used in scientific research involving high-intensity lasers, astrophysics, and nuclear physics to quantify extremely large power outputs.
