Convert joule/second to attojoule/second

Please provide values below to convert joule/second [J/s] to attojoule/second [aJ/s], or Convert attojoule/second to joule/second.

1 J/s = 1.0000e+18 aJ/s. To convert joule/second to attojoule/second, multiply the value by 1.0000e+18; to go the other way, divide by it (1 aJ/s = 1.0000e-18 J/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 J/s = 1.0000e+18 aJ/s
  • 1 aJ/s = 1.0000e-18 J/s
  • 10 J/s = 1.0000e+19 aJ/s
  • 100 J/s = 1.0000e+20 aJ/s



How to Convert Joule/second to Attojoule/second

1 J/s = 1e+18 aJ/s

Example: convert 15 J/s to aJ/s:
15 J/s = 15 × 1e+18 aJ/s = 1.5e+19 aJ/s

Joule/second

The joule per second (J/s) is a unit of power representing the rate at which energy is transferred or converted, equivalent to one watt.

History/Origin

The joule per second has been used as a measure of power since the adoption of the SI system, where the watt (W) became the standard unit of power, with 1 J/s = 1 W.

Current Use

J/s is primarily used in scientific and engineering contexts to quantify power, especially in physics and electrical engineering, often interchangeably with watts.


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.


Frequently Asked Questions
