Convert calorie (th)/second to attojoule/second
Please provide values below to convert calorie (th)/second [cal(th)/s] to attojoule/second [aJ/s], or Convert attojoule/second to calorie (th)/second.
How to Convert Calorie (Th)/second to Attojoule/second
1 cal(th)/s = 4.184e+21 aJ/s
Example: convert 15 cal(th)/s to aJ/s:
15 cal(th)/s = 15 × 4.184e+21 aJ/s = 6.276e+22 aJ/s

Calorie (Th)/second
Calorie (th)/second (cal(th)/s) is a unit of power representing the rate at which thermal calories are transferred or converted per second.
History/Origin
The calorie (th), or thermochemical calorie, was historically used to quantify energy in thermodynamics and nutrition. Its use in power measurement, such as cal(th)/s, emerged in scientific contexts to express thermal energy transfer rates before the adoption of the watt as the standard SI unit.
Current Use
Today, cal(th)/s is rarely used in scientific practice, having been largely replaced by watts (W). It may still appear in specialized fields or historical references related to thermal energy transfer rates.
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.
