Convert horsepower (water) to erg/second
Please provide values below to convert horsepower (water) [hp (water)] to erg/second [erg/s], or Convert erg/second to horsepower (water).
How to Convert Horsepower (Water) to Erg/second
1 hp (water) = 7460430000 erg/s
Example: convert 15 hp (water) to erg/s:
15 hp (water) = 15 × 7460430000 erg/s = 111906450000 erg/s

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.
Erg/second
The erg/second (erg/s) is a unit of power representing the rate of energy transfer or conversion, where one erg per second equals the transfer of one erg of energy per second.
History/Origin
The erg is an older CGS (centimeter-gram-second) unit of energy, introduced in the early 20th century for scientific calculations. The erg/second was used in physics to quantify power in contexts where the CGS system was prevalent, especially in astrophysics and theoretical physics.
Current Use
Today, the erg/second is rarely used outside specialized scientific fields; the SI unit watt (W) is preferred for measuring power. However, erg/s may still be encountered in historical data, astrophysics, or when working with CGS-based calculations.
