Convert kilowatt to femtojoule/second
Please provide values below to convert kilowatt [kW] to femtojoule/second [fJ/s], or Convert femtojoule/second to kilowatt.
How to Convert Kilowatt to Femtojoule/second
1 kW = 1e+18 fJ/s
Example: convert 15 kW to fJ/s:
15 kW = 15 × 1e+18 fJ/s = 1.5e+19 fJ/s

Kilowatt
A kilowatt (kW) is a unit of power equal to 1,000 watts, used to measure the rate of energy transfer or consumption.
History/Origin
The kilowatt was introduced as part of the metric system to provide a practical unit for measuring larger power outputs, especially in engineering and electrical contexts, and has been widely adopted since the 20th century.
Current Use
The kilowatt is commonly used today to specify the power output of engines, electrical appliances, and power generation facilities, as well as in billing for electricity consumption and capacity ratings.
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.
