Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
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.
