What Is This Tool?
This unit converter transforms power measurements from metric horsepower into joule per second [J/s], providing a standardized representation of mechanical power commonly used in automotive, industrial, and electrical contexts.
How to Use This Tool?
-
Input the value in metric horsepower you want to convert
-
Select 'horsepower (metric)' as the source unit and 'joule/second [J/s]' as the target unit
-
Execute the conversion to obtain the equivalent power in joule per second [J/s]
-
Use the result for standardized power comparisons and technical purposes

Examples
-
2 horsepower (metric) equals 1470.9975 joule/second [J/s]
-
0.5 horsepower (metric) is converted to 367.749375 joule/second [J/s]
Common Use Cases
-
Rating engine power for vehicles in European and Asian markets
-
Specifying outputs of small industrial motors, pumps, and generators in datasheets
-
Comparing vehicle performance metrics in brochures and specifications
-
Expressing electrical power consumption for appliances and devices
-
Analyzing mechanical power in engines, turbines, and electric motors
-
Quantifying heat transfer rates in thermodynamics and HVAC systems
Tips & Best Practices
-
Always use joule/second [J/s] for scientific and engineering calculations requiring SI units
-
Verify conversions carefully to avoid rounding errors due to the exact conversion factor
-
Apply the tool for consistent power rating communication across different technical fields
-
Be mindful that metric horsepower is not an official SI unit but is widely used in practical contexts
Limitations
-
Metric horsepower is not part of the SI unit system and may cause inconsistencies in strictly SI-based standards
-
Exact conversion requires using 735.49875 joule/second per horsepower (metric); rounding can reduce precision
-
For highly accurate measurements, joule/second (watt) is preferred over horsepower units
Frequently Asked Questions
-
What does one metric horsepower represent?
-
One metric horsepower equals exactly 735.49875 watts and measures the rate of energy transfer or mechanical work done.
