Convert horsepower (boiler) to femtowatt
Please provide values below to convert horsepower (boiler) [hp (boiler)] to femtowatt [fW], or Convert femtowatt to horsepower (boiler).
How to Convert Horsepower (Boiler) to Femtowatt
1 hp (boiler) = 9.81e+18 fW
Example: convert 15 hp (boiler) to fW:
15 hp (boiler) = 15 × 9.81e+18 fW = 1.4715e+20 fW

Horsepower (Boiler)
Horsepower (boiler) is a unit of power used to measure the rate of energy transfer, specifically indicating the power of steam boilers, equivalent to approximately 33,475 watts.
History/Origin
The boiler horsepower was developed in the late 19th century to standardize the measurement of steam boiler capacity, primarily in the United States, and has been used historically in engineering and industrial applications to quantify boiler power output.
Current Use
Today, boiler horsepower is primarily used in the United States for specifying the capacity of steam boilers in industrial and commercial settings, although it has largely been replaced by SI units like watts or kilowatts in most regions.
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.
