Convert calorie (IT)/hour to attojoule/second
Please provide values below to convert calorie (IT)/hour [cal/h] to attojoule/second [aJ/s], or Convert attojoule/second to calorie (IT)/hour.
1 cal/h = 1.1630e+18 aJ/s. To convert calorie (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 cal/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 cal/h = 1.1630e+18 aJ/s
- 1 aJ/s = 8.5985e-19 cal/h
- 10 cal/h = 1.1630e+19 aJ/s
- 100 cal/h = 1.1630e+20 aJ/s
How to Convert Calorie (It)/hour to Attojoule/second
1 cal/h = 1.163e+18 aJ/s
Example: convert 15 cal/h to aJ/s:
15 cal/h = 15 × 1.163e+18 aJ/s = 1.7445e+19 aJ/s

Calorie (It)/hour
Calorie per hour (cal/h) is a unit of power that measures the rate at which energy in calories is transferred or consumed over time.
History/Origin
The calorie has been used historically in nutrition and thermodynamics to quantify energy. The cal/h unit emerged in contexts where energy transfer rates were expressed in calories per hour, particularly in heating and metabolic studies.
Current Use
Cal/h is used in specific scientific and engineering applications, such as measuring heat transfer rates, metabolic rates, and in some thermal engineering contexts, although it is less common than SI units like watts.
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.
