What Is This Tool?

This converter assists in transforming power measurements from electric horsepower, used to rate electric motors, to water horsepower, which measures hydraulic power related to water flow and pressure. It supports accurate comparison and calculation for engineering and design tasks involving motors and pumps.

How to Use This Tool?

  • Enter the value in horsepower (electric) you want to convert
  • Select horsepower (electric) as the source unit
  • Choose horsepower (water) as the target unit
  • Execute the conversion to see the equivalent hydraulic power
  • Apply the converted value for equipment sizing and design comparisons

Key Features

  • Converts between horsepower (electric) and horsepower (water) units
  • Based on established conversion rates for power comparison
  • Uses exact definitions relevant to electric motors and hydraulic systems
  • Useful for aligning motor ratings with pump and water system requirements
  • Suitable for industrial, irrigation, HVAC, and hydropower fields

Examples

  • 1 horsepower (electric) equals 0.9999423626 horsepower (water)
  • 5 horsepower (electric) equals 4.999711813 horsepower (water)

Common Use Cases

  • Matching electric motor ratings with hydraulic power needs in pump design
  • Sizing motor controllers and electrical supply capacities for industrial equipment
  • Designing HVAC, irrigation, and municipal water supply pump systems
  • Estimating hydraulic power available from low-head water sources for micro-hydropower
  • Calculating required motor power for specified water flow and head in piping systems

Tips & Best Practices

  • Use precise input data for flow rate, head, and fluid specific gravity when applying water horsepower calculations
  • Ensure the conversion matches your specific application context, especially in pump and motor specification
  • Check that motor controllers and electrical systems are sized appropriately for the converted power rating
  • Consider theoretical nature of water horsepower and verify practical efficiency separately
  • Maintain standard conditions assumptions when using this converter

Limitations

  • Assumes standard operating conditions without accounting for losses or inefficiencies
  • Water horsepower is a theoretical measure requiring accurate flow and head data for real-world accuracy
  • Does not reflect mechanical transmission or fluid dynamic losses in practical systems

Frequently Asked Questions

What is electric horsepower used for?
Electric horsepower rates electric motors and drives, representing power output typically defined as exactly 746 watts.

How is water horsepower different?
Water horsepower measures the mechanical power needed to move water against certain head and flow conditions, reflecting hydraulic power.

Why convert between these two units?
Converting helps align electric motor ratings with hydraulic power requirements, aiding in equipment sizing and efficiency calculations.

Key Terminology

Horsepower (electric)
A unit of power for electric motors defined as exactly 746 watts, used in motor rating and specifications.
Horsepower (water)
Theoretical mechanical power to move water against a specific head and flow, used in hydraulic and pump system design.
Conversion Rate
The factor used to translate electric horsepower into water horsepower, here equal to 0.9999423626.
