Convert horsepower (water) to attojoule/second
Please provide values below to convert horsepower (water) [hp (water)] to attojoule/second [aJ/s], or Convert attojoule/second to horsepower (water).
1 hp (water) = 7.4604e+20 aJ/s. To convert horsepower (water) to attojoule/second, multiply the value by 7.4604e+20; to go the other way, divide by it (1 aJ/s = 1.3404e-21 hp (water)). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

Horsepower (Water)
Horsepower (water) is a unit of power used to measure the rate of water flow or energy transfer, based on the power exerted by a water stream.
History/Origin
The water horsepower originated in the 19th century as a way to quantify the power of water wheels and turbines, with its value historically linked to the energy produced by a specific flow of water under certain conditions.
Current Use
Today, water horsepower is primarily used in hydraulic engineering and water power industries to specify the capacity of water turbines, pumps, and other hydraulic equipment.
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.
