Convert kilojoule/hour to attojoule/second
Please provide values below to convert kilojoule/hour [kJ/h] to attojoule/second [aJ/s], or Convert attojoule/second to kilojoule/hour.
1 kJ/h = 2.7778e+17 aJ/s. To convert kilojoule/hour to attojoule/second, multiply the value by 2.7778e+17; to go the other way, divide by it (1 aJ/s = 3.6000e-18 kJ/h). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Kilojoule/hour
A kilojoule per hour (kJ/h) is a unit of power representing the amount of energy in kilojoules transferred or converted per hour.
History/Origin
The kilojoule per hour has been used as a measure of power in contexts where energy transfer rates are expressed over time, particularly in engineering and scientific applications, though it is less common than standard SI units like watts.
Current Use
kJ/h is used in specific fields such as thermodynamics and energy management to quantify energy transfer rates, especially in systems where energy is measured in kilojoules and the rate is expressed per hour, though it is often converted to watts for standardization.
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.
