Convert attojoule/second to kilocalorie (th)/second
Please provide values below to convert attojoule/second [aJ/s] to kilocalorie (th)/second [kcal(th)/s], or Convert kilocalorie (th)/second to attojoule/second.
How to Convert Attojoule/second to Kilocalorie (Th)/second
1 aJ/s = 2.39005736137667e-22 kcal(th)/s
Example: convert 15 aJ/s to kcal(th)/s:
15 aJ/s = 15 × 2.39005736137667e-22 kcal(th)/s = 3.58508604206501e-21 kcal(th)/s

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.
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.
