Please provide values below to convert kilocalorie (IT)/hour [kcal/h] to femtojoule/second [fJ/s], or Convert femtojoule/second to kilocalorie (IT)/hour.
How to Convert Kilocalorie (It)/hour to Femtojoule/second
1 kcal/h = 1.163e+15 fJ/s
Example: convert 15 kcal/h to fJ/s:
15 kcal/h = 15 × 1.163e+15 fJ/s = 1.7445e+16 fJ/s

Kilocalorie (It)/hour
Kilocalorie per hour (kcal/h) is a unit of power representing the rate at which energy in kilocalories is transferred or converted per hour.
History/Origin
The kilocalorie, often used in nutrition and energy measurement, has been adopted as a unit of energy. Its use in power measurement, such as kcal/h, emerged in contexts like thermal and caloric power calculations, especially in fields related to heating and energy transfer.
Current Use
kcal/h is used in applications involving thermal power, such as heating systems, calorimetry, and energy transfer calculations where energy flow is expressed in kilocalories per hour.
Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
