Convert horsepower (water) to gigajoule/second
Please provide values below to convert horsepower (water) [hp (water)] to gigajoule/second [GJ/s], or Convert gigajoule/second to horsepower (water).
1 hp (water) = 7.46043e-07 GJ/s. To convert horsepower (water) to gigajoule/second, multiply the value by 7.46043e-07; to go the other way, divide by it (1 GJ/s = 1340405.31176 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.
Gigajoule/second
A gigajoule per second (GJ/s) is a unit of power equivalent to one gigajoule of energy transferred or converted per second.
History/Origin
The gigajoule per second emerged as a larger-scale unit of power measurement, primarily used in scientific and engineering contexts to quantify high power levels, especially in energy production and consumption. It is derived from the SI unit joule and the prefix giga, combined with the second as the time unit.
Current Use
GJ/s is used in fields such as energy industry, power generation, and large-scale energy transfer analysis to express high power rates, often in the context of power plants, energy infrastructure, and large energy projects.
