Convert kilocalorie (IT)/minute to exajoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to exajoule/second [EJ/s], or Convert exajoule/second to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Exajoule/second
1 kcal/min = 6.978e-17 EJ/s
Example: convert 15 kcal/min to EJ/s:
15 kcal/min = 15 × 6.978e-17 EJ/s = 1.0467e-15 EJ/s

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.
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.
