What Is This Tool?
This tool converts power measurements from dekajoule per second (daJ/s), an SI-derived metric unit, to mechanical horsepower (550 foot-pound-force per second), an imperial unit commonly used in automotive and small engine contexts.
How to Use This Tool?
-
Enter the power value in dekajoule per second (daJ/s).
-
Select the input unit as dekajoule/second and output unit as horsepower (550 ft*lbf/s).
-
Click convert to see the equivalent horsepower value instantly.
Key Features
-
Converts power units from dekajoule/second to mechanical horsepower (550 ft*lbf/s).
-
Supports easy switching between metric and imperial power units.
-
Useful for engineering, automotive, and equipment power comparisons.
-
Browser-based and straightforward to use with instant results.
Examples
-
10 daJ/s converts to approximately 0.1341 horsepower (550 ft*lbf/s).
-
50 daJ/s converts to approximately 0.6705 horsepower (550 ft*lbf/s).
Common Use Cases
-
Translating power ratings of household lighting or appliances from metric to imperial units.
-
