Convert kilocalorie (th)/second to attojoule/second
Please provide values below to convert kilocalorie (th)/second [kcal(th)/s] to attojoule/second [aJ/s], or Convert attojoule/second to kilocalorie (th)/second.
1 kcal(th)/s = 4.1840e+21 aJ/s. To convert kilocalorie (th)/second to attojoule/second, multiply the value by 4.1840e+21; to go the other way, divide by it (1 aJ/s = 2.3901e-22 kcal(th)/s). 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(th)/s = 4.1840e+21 aJ/s
- 1 aJ/s = 2.3901e-22 kcal(th)/s
- 10 kcal(th)/s = 4.1840e+22 aJ/s
- 100 kcal(th)/s = 4.1840e+23 aJ/s
How to Convert Kilocalorie (Th)/second to Attojoule/second
1 kcal(th)/s = 4.184e+21 aJ/s
Example: convert 15 kcal(th)/s to aJ/s:
15 kcal(th)/s = 15 × 4.184e+21 aJ/s = 6.276e+22 aJ/s

Kilocalorie (Th)/second
A kilocalorie (th)/second (kcal(th)/s) is a unit of power representing the rate at which energy in kilocalories per second is transferred or converted.
History/Origin
The kilocalorie (th) is a traditional unit of energy used primarily in nutrition and thermodynamics, with 'th' indicating the thermochemical definition. Its use in power measurements, such as kcal(th)/s, is less common and primarily for specialized scientific contexts.
Current Use
The unit kcal(th)/s is rarely used in modern practice; power is more commonly expressed in watts. When used, it typically appears in scientific research involving energy transfer rates in thermochemical processes or specialized engineering applications.
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.
