Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
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.
