Convert joule/hour to attojoule/second

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

1 J/h = 2.7778e+14 aJ/s. To convert joule/hour to attojoule/second, multiply the value by 2.7778e+14; to go the other way, divide by it (1 aJ/s = 3.6000e-15 J/h). 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/h = 2.7778e+14 aJ/s
  • 1 aJ/s = 3.6000e-15 J/h
  • 10 J/h = 2.7778e+15 aJ/s
  • 100 J/h = 2.7778e+16 aJ/s

Joule/hour

A joule per hour (J/h) is a unit of power representing the amount of energy (in joules) transferred or converted per hour.

History/Origin

The joule per hour has been used as a measure of power in various scientific and engineering contexts, especially where energy transfer rates are expressed over longer periods. It is derived from the SI unit of energy, the joule, divided by time in hours.

Current Use

Joule per hour is occasionally used in fields like heating, energy consumption, and industrial processes to quantify power over extended durations, though it is less common than watts for standard power measurements.


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.
