Convert Btu (IT)/second to femtowatt
Please provide values below to convert Btu (IT)/second [Btu/s] to femtowatt [fW], or Convert femtowatt to Btu (IT)/second.
1 Btu/s = 1.0551e+18 fW. To convert Btu (IT)/second to femtowatt, multiply the value by 1.0551e+18; to go the other way, divide by it (1 fW = 9.4782e-19 Btu/s). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Btu/s = 1.0551e+18 fW
- 1 fW = 9.4782e-19 Btu/s
- 10 Btu/s = 1.0551e+19 fW
- 100 Btu/s = 1.0551e+20 fW

Btu (It)/second
Btu per second (Btu/s) is a unit of power representing the rate of energy transfer or conversion, where one British thermal unit (Btu) is transferred or converted every second.
History/Origin
The Btu (British thermal unit) has been used historically to measure energy, especially in heating and cooling industries. The use of Btu per second as a power unit emerged to quantify energy transfer rates in engineering and scientific contexts, aligning with the broader adoption of the Btu in energy measurement.
Current Use
Btu/s is used primarily in engineering and energy industries to specify power levels, such as in heating, cooling, and energy transfer systems, although it is less common than SI units like watts.
Femtowatt
A femtowatt (fW) is a unit of power equal to 10^-15 watts, representing an extremely small amount of power.
History/Origin
The femtowatt was introduced as part of the SI prefixes to measure very small quantities of power, particularly in scientific and technological contexts, gaining recognition as the need to quantify minute power levels grew.
Current Use
Femtowatts are used in fields such as quantum physics, nanotechnology, and optical measurements, where precise measurement of extremely low power levels is required.
