Convert horsepower (boiler) to attojoule/second
Please provide values below to convert horsepower (boiler) [hp (boiler)] to attojoule/second [aJ/s], or Convert attojoule/second to horsepower (boiler).
How to Convert Horsepower (Boiler) to Attojoule/second
1 hp (boiler) = 9.81e+21 aJ/s
Example: convert 15 hp (boiler) to aJ/s:
15 hp (boiler) = 15 × 9.81e+21 aJ/s = 1.4715e+23 aJ/s

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States for specifying the capacity of steam boilers in industrial and commercial settings, although it has largely been replaced by SI units like watts or kilowatts in most regions.
Attojoule/second
An attojoule per second (aJ/s) is a unit of power representing the rate of energy transfer or conversion of one attojoule (10^-18 joules) per second.
History/Origin
The attojoule is a relatively recent SI prefix introduced to measure extremely small quantities of energy, and its use in power units like aJ/s has emerged with advancements in nanotechnology and quantum physics, though it remains a specialized unit with limited historical usage.
Current Use
The aJ/s is used in scientific research involving extremely low power measurements, such as in quantum physics, nanotechnology, and energy transfer studies at the atomic or molecular scale.
