What is a horsepower hour?

A horsepower hour is a unit of energy representing one horsepower of power applied continuously for one hour, mainly used for mechanical work.

Why convert horsepower hour to megawatt-hour?

This conversion helps relate mechanical energy output to large-scale electrical energy units, useful in energy engineering and industrial energy comparisons.

Does this tool account for different horsepower definitions?

No, it assumes the mechanical (imperial) horsepower standard for conversion accuracy.

What Is This Tool?

This converter tool helps transform energy values measured in horsepower hour (hp*h), a unit commonly used for mechanical work, into megawatt-hour (MW*h), a unit suitable for large-scale electrical energy analysis.

How to Use This Tool?

Enter the energy value in horsepower hour you want to convert
Select horsepower hour as the starting unit and megawatt-hour as the target unit
Click the convert button to see the equivalent energy in megawatt-hour
Review the converted value and use it for your energy calculations or reporting

Key Features

Converts mechanical energy units (horsepower hour) into electrical energy units (megawatt-hour)
Supports energy conversions relevant to engineering, power generation, and industrial analysis
Uses the mechanical horsepower definition as the basis for conversion
Includes example calculations to assist users
Browser-based and simple to use

Examples

Converting 10 hp*h results in approximately 0.007456999 MW*h
Converting 100 hp*h results in approximately 0.07456999 MW*h

Common Use Cases

Translating mechanical work output from engines into electrical energy units for grid analysis
Bridging legacy mechanical power measurements with modern electrical energy accounting
Reporting and comparing power plant and large-scale energy storage capacities
Evaluating energy consumption and generation within industrial or utility contexts

Tips & Best Practices

Verify the horsepower definition being used matches the mechanical horsepower standard for accurate conversions
Use this conversion for comparatively small mechanical energy values when relating to large electrical units
Be mindful of numerical scale differences to avoid rounding errors
Double-check conversion results in the context of your specific energy units and applications

Limitations

Conversion accuracy depends on the mechanical horsepower definition assumed
Large differences in unit scale may introduce potential rounding errors
Megawatt-hours are meant for large energy quantities, so converted values from hp*h tend to be small
Different horsepower variants (metric, PS) are not accounted for in this converter
