Convert joule/second to femtojoule/second
Please provide values below to convert joule/second [J/s] to femtojoule/second [fJ/s], or Convert femtojoule/second to joule/second.
How to Convert Joule/second to Femtojoule/second
1 J/s = 1e+15 fJ/s
Example: convert 15 J/s to fJ/s:
15 J/s = 15 × 1e+15 fJ/s = 1.5e+16 fJ/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.
Femtojoule/second
A femtojoule per second (fJ/s) is a unit of power representing the rate of energy transfer of one femtojoule (10^-15 joules) per second.
History/Origin
The femtojoule/second unit emerged with the development of high-precision measurements in nanotechnology and quantum physics, where extremely small energy transfer rates are relevant. It is derived from the SI units of energy (joule) and time (second), with 'femto' denoting 10^-15.
Current Use
The femtojoule/second is used in scientific research to quantify very small power levels, particularly in fields like nanotechnology, quantum computing, and molecular physics, where energy transfer rates are extremely low.
