Convert kilocalorie (IT)/second to attojoule/second

Please provide values below to convert kilocalorie (IT)/second [kcal/s] to attojoule/second [aJ/s], or Convert attojoule/second to kilocalorie (IT)/second.

1 kcal/s = 4.1868e+21 aJ/s. To convert kilocalorie (IT)/second to attojoule/second, multiply the value by 4.1868e+21; to go the other way, divide by it (1 aJ/s = 2.3885e-22 kcal/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/s = 4.1868e+21 aJ/s
  • 1 aJ/s = 2.3885e-22 kcal/s
  • 10 kcal/s = 4.1868e+22 aJ/s
  • 100 kcal/s = 4.1868e+23 aJ/s

Kilocalorie (It)/second

A kilocalorie per second (kcal/s) is a unit of power representing the rate at which energy in kilocalories is transferred or converted per second.

History/Origin

The kilocalorie, often used in nutrition and thermodynamics, has been a standard unit of energy measurement. Its use in power calculations, such as kcal/s, emerged in contexts requiring energy transfer rates, though it is less common than SI units like watts.

Current Use

Kcal/s is primarily used in specialized fields like thermodynamics and calorimetry to quantify energy transfer rates, especially in contexts involving heat transfer and energy consumption, though it is less prevalent than SI units.


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.
