Convert attojoule/second to kilocalorie (th)/second
Enter a value below to convert attojoule/second [aJ/s] to kilocalorie (th)/second [kcal(th)/s]. Reverse conversion: Convert kilocalorie (th)/second to attojoule/second.
1 aJ/s = 2.3901e-22 kcal(th)/s. To convert attojoule/second to kilocalorie (th)/second, multiply the value by 2.3901e-22; to go the other way, divide by it (1 kcal(th)/s = 4.1840e+21 aJ/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Attojoule/second: Definition and Use
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: Definition and Use
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.
