Convert horsepower (water) to exawatt
Please provide values below to convert horsepower (water) [hp (water)] to exawatt [EW], or Convert exawatt to horsepower (water).
1 hp (water) = 7.4604e-16 EW. To convert horsepower (water) to exawatt, multiply the value by 7.4604e-16; to go the other way, divide by it (1 EW = 1.3404e+15 hp (water)). Both units measure power and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 hp (water) = 7.4604e-16 EW
- 1 EW = 1.3404e+15 hp (water)
- 10 hp (water) = 7.4604e-15 EW
- 100 hp (water) = 7.4604e-14 EW
How to Convert Horsepower (Water) to Exawatt
1 hp (water) = 7.46043e-16 EW
Example: convert 15 hp (water) to EW:
15 hp (water) = 15 × 7.46043e-16 EW = 1.1190645e-14 EW

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.
Exawatt
An exawatt (EW) is a unit of power equal to 10^18 watts.
History/Origin
The exawatt is part of the SI prefix system, introduced to represent extremely large power quantities, especially in theoretical physics and astrophysics, as the need to express vast energy outputs grew.
Current Use
Exawatts are primarily used in scientific contexts to describe the power output of large-scale phenomena such as stars and cosmic events; they are rarely used in everyday measurements.
