Calorie (It)/second
Calorie per second (cal/s) is a unit of power representing the rate at which energy in calories is transferred or converted per second.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of one gram of water by one degree Celsius, has been used in various contexts including nutrition and thermodynamics. The use of calories per second as a power unit became common in scientific and engineering fields to quantify energy transfer rates before the adoption of the SI unit watt.
Current Use
Calorie per second is primarily used in scientific research, thermodynamics, and certain engineering applications to measure power, especially in contexts where energy transfer in calories is relevant. It is less common in everyday use, having been largely replaced by the watt (W) in SI units.
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.
