Please provide values below to convert kilocalorie (th)/hour [kcal(th)/h] to exajoule/second [EJ/s], or Convert exajoule/second to kilocalorie (th)/hour.
How to Convert Kilocalorie (Th)/hour to Exajoule/second
1 kcal(th)/h = 1.16222222e-18 EJ/s
Example: convert 15 kcal(th)/h to EJ/s:
15 kcal(th)/h = 15 × 1.16222222e-18 EJ/s = 1.74333333e-17 EJ/s

Kilocalorie (Th)/hour
A kilocalorie (th)/hour (kcal(th)/h) is a unit of power representing the rate at which energy in kilocalories per hour is transferred or converted.
History/Origin
The kilocalorie, often used in nutrition and energy measurement, has been adapted into various units including the thermochemical kilocalorie (kcal(th)). Its use in power measurement, such as kcal(th)/h, is primarily for specialized scientific and engineering applications, integrating energy units with time to express power.
Current Use
The kcal(th)/h unit is used in contexts requiring the measurement of energy transfer rates in thermochemical terms, such as in thermal engineering, calorimetry, and energy efficiency assessments where energy flow is expressed in kilocalories per hour.
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.
