Click convert to see the equivalent energy transfer rate.

Key Features

Converts horsepower (hp, hp (UK)) to joule per hour (J/h) accurately based on defined rates.
Supports understanding power output in terms of hourly energy transfer.
Useful for automotive, mechanical, and electrical applications.
Browser-based and straightforward user interface.

Examples

2 horsepower converts to 5,369,039.0753924 joule/hour.
0.5 horsepower converts to 1,342,259.7688481 joule/hour.

Common Use Cases

Rating engine power in automotive and motorcycle specifications.
Determining energy consumption rates over hours for electric motors and pumps.
Measuring slow thermal losses in laboratory experiments reported hourly.
Comparing marine engines and industrial machinery output.

Tips & Best Practices

Verify which horsepower variant applies before conversion for accurate results.
Use joule/hour units primarily for low power or long-duration energy transfer scenarios.
Avoid using joule/hour to represent high horsepower values due to large resulting numbers.

Limitations

Different types of horsepower exist, so conversion accuracy varies with the chosen variant.
Joule per hour is suitable for representing low power, making it impractical for very high power values.
Conversion results depend on measurement precision and unit definitions.
