Convert kilocalorie (IT)/hour to attojoule/second
Please provide values below to convert kilocalorie (IT)/hour [kcal/h] to attojoule/second [aJ/s], or Convert attojoule/second to kilocalorie (IT)/hour.
1 kcal/h = 1.1630e+18 aJ/s. To convert kilocalorie (IT)/hour to attojoule/second, multiply the value by 1.1630e+18; to go the other way, divide by it (1 aJ/s = 8.5985e-19 kcal/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kcal/h = 1.1630e+18 aJ/s
- 1 aJ/s = 8.5985e-19 kcal/h
- 10 kcal/h = 1.1630e+19 aJ/s
- 100 kcal/h = 1.1630e+20 aJ/s
How to Convert Kilocalorie (It)/hour to Attojoule/second
1 kcal/h = 1.163e+18 aJ/s
Example: convert 15 kcal/h to aJ/s:
15 kcal/h = 15 × 1.163e+18 aJ/s = 1.7445e+19 aJ/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.
Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
