Convert kilocalorie (IT)/minute to terajoule/second
Please provide values below to convert kilocalorie (IT)/minute [kcal/min] to terajoule/second [TJ/s], or Convert terajoule/second to kilocalorie (IT)/minute.
How to Convert Kilocalorie (It)/minute to Terajoule/second
1 kcal/min = 6.978e-11 TJ/s
Example: convert 15 kcal/min to TJ/s:
15 kcal/min = 15 × 6.978e-11 TJ/s = 1.0467e-09 TJ/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.
Terajoule/second
A terajoule per second (TJ/s) is a unit of power equivalent to one trillion joules of energy transferred or converted per second.
History/Origin
The terajoule per second is derived from the SI units of energy (joule) and time (second), with 'tera' indicating a factor of 10^12. It is used in scientific and engineering contexts to measure very high power levels, especially in fields like astrophysics and energy production.
Current Use
TJ/s is used to quantify extremely high power outputs, such as in large-scale energy systems, astrophysical phenomena, and nuclear reactions, where conventional units like watts are insufficient to express the magnitude.
