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.
Exawatt
An exawatt (EW) is a unit of power equal to 10^18 watts.
History/Origin
The exawatt is part of the SI prefix system, introduced to represent extremely large power quantities, especially in theoretical physics and astrophysics, as the need to express vast energy outputs grew.
Current Use
Exawatts are primarily used in scientific contexts to describe the power output of large-scale phenomena such as stars and cosmic events; they are rarely used in everyday measurements.
