Convert femtojoule/second to Btu (IT)/hour
Enter a value below to convert femtojoule/second [fJ/s] to Btu (IT)/hour [Btu/h]. Reverse conversion: Convert Btu (IT)/hour to femtojoule/second.
1 fJ/s = 3.4121e-15 Btu/h. To convert femtojoule/second to Btu (IT)/hour, multiply the value by 3.4121e-15; to go the other way, divide by it (1 Btu/h = 2.9307e+14 fJ/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Femtojoule/second: Definition and Use
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.
Btu (It)/hour: Definition and Use
Btu (IT)/hour (Btu/h) is a unit of power that measures the rate of energy transfer, specifically the amount of British thermal units (IT) transferred per hour.
History/Origin
The Btu (IT) originated from the British thermal unit used in the United States and was standardized for industrial and engineering purposes. The per-hour notation became common in applications requiring power measurement, especially in heating and cooling systems.
Current Use
Btu/h is widely used in heating, ventilation, and air conditioning (HVAC) industries to specify the capacity of heating and cooling equipment, as well as in energy analysis and thermodynamics.
