What Is This Tool?

This online unit converter transforms power values expressed in horsepower (water) to their equivalent in horsepower (electric). It supports engineers and technicians who need to match hydraulic power requirements with electric motor ratings for various water supply and pump applications.

How to Use This Tool?

  • Enter the power value measured in horsepower (water) into the input field.
  • Select horsepower (water) as the starting unit and horsepower (electric) as the target unit.
  • Click convert to get the equivalent power value in horsepower (electric).
  • Use the converted value for motor sizing, pump efficiency estimation, or equipment specification purposes.

Key Features

  • Converts power from horsepower (water) to horsepower (electric) using an exact conversion rate.
  • Supports applications in pump selection, municipal water supply, HVAC system design, and micro-hydropower turbine projects.
  • Browser-based tool requiring no installation, easy and quick to use.
  • Uses unit definitions aligned with standard U.S. customary engineering practices.

Examples

  • Convert 5 horsepower (water): 5 × 1.0000576408 = 5.000288204 horsepower (electric).
  • Convert 10 horsepower (water): 10 × 1.0000576408 = 10.000576408 horsepower (electric).

Common Use Cases

  • Matching hydraulic power requirements to electric motor output ratings for pump systems.
  • Pump design and selection for irrigation, municipal water supply, and HVAC engineering.
  • Estimating the hydraulic power available from low-head water sources for micro-hydropower turbines.
  • Sizing motor controllers and electrical supply equipment based on electric horsepower specifications.

Tips & Best Practices

  • Always verify standard water properties and motor ratings when performing conversions.
  • Use this tool to assist in precise engineering calculations and equipment specification.
  • Check results against equipment nameplates and manufacturer data for confirmation.
  • Consider the small difference between units to ensure accurate motor sizing.

Limitations

  • Conversion calculations presume standard conditions for water properties and motor ratings.
  • Real-world variations in fluid characteristics or motor efficiency are not accounted for.
  • Differences between horsepower (water) and horsepower (electric) values are minimal but important for accuracy.

Frequently Asked Questions

What is the main difference between horsepower (water) and horsepower (electric)?
Horsepower (water) measures hydraulic power related to moving water, while horsepower (electric) rates electric motor power output defined as exactly 746 watts.

Why is it important to convert between these two horsepower units?
Converting ensures the proper sizing and efficient operation of electric motors relative to the hydraulic power they must provide in water-moving systems.

Does this conversion factor change with different water properties or motors?
The given conversion assumes standard water properties and motor ratings; actual conditions may cause slight variations in power requirements.

Key Terminology

Horsepower (water)
The mechanical power associated with moving a volume of water against a specific head, calculated based on flow, head, and water properties.
Horsepower (electric)
A power unit rating electric motors, defined as exactly 746 watts, representing the equivalent mechanical work output.
Conversion Rate
The factor used to translate power values from horsepower (water) to horsepower (electric), which is 1.0000576408.
