How to Convert Calorie (Th)/hour to Exajoule/second
1 cal(th)/h = 1.16222222e-18 EJ/s
Example: convert 15 cal(th)/h to EJ/s:
15 cal(th)/h = 15 × 1.16222222e-18 EJ/s = 1.74333333e-17 EJ/s

Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
Exajoule/second
An exajoule per second (EJ/s) is a unit of power representing the transfer or conversion of one exajoule of energy every second.
History/Origin
The exajoule (EJ) 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 units like EJ/s emerged with the development of large-scale energy measurement, particularly in fields such as astrophysics and energy production, to quantify extremely high power levels.
Current Use
EJ/s is used primarily in theoretical and large-scale energy discussions, such as in astrophysics, planetary science, and global energy consumption analysis, where extremely high power levels are involved.
