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.
Kilocalorie (It)/minute
A unit of power representing the energy expended or transferred at a rate of one kilocalorie per minute.
History/Origin
The kilocalorie (kcal) has historically been used to measure energy in food and nutrition, while the minute as a time unit has been standard in timekeeping. Combining these, kcal/min was used to quantify power, especially in contexts like metabolic rates and energy expenditure, before the widespread adoption of the watt as the SI unit of power.
Current Use
The kcal/min is primarily used in fields such as physiology and sports science to express rates of energy expenditure, though it is less common today with the adoption of the watt (W) as the standard SI unit of power.
