Petajoule/second
A petajoule per second (PJ/s) is a unit of power representing the transfer or conversion of one petajoule of energy every second.
History/Origin
The petajoule (PJ) is a metric unit of energy introduced as part of the International System of Units (SI) to measure large quantities of energy. The concept of power in terms of energy per unit time has been fundamental in physics, with the watt (W) as the SI base unit. The petajoule per second emerged as a large-scale unit for high-energy power measurements, especially in fields like energy production and scientific research.
Current Use
Petajoule per second is used in scientific and engineering contexts to quantify extremely high power levels, such as in nuclear energy, large-scale power generation, and astrophysics. It is also used in theoretical and large-scale energy calculations where conventional units like watts are insufficient.
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.
