What Is This Tool?
This converter allows you to convert power values from horsepower (550 ft*lbf/s), an imperial unit defined by James Watt, into kilojoule per second (kJ/s), a metric unit equivalent to kilowatt. It is useful for comparing power ratings and expressing energy transfer rates across different measurement systems.
How to Use This Tool?
-
Enter the power value in horsepower (550 ft*lbf/s) into the converter.
-
Select horsepower as the 'from' unit and kilojoule/second [kJ/s] as the 'to' unit.
-
View the converted power measurement expressed in kilojoule per second.
Key Features
-
Converts mechanical horsepower defined as 550 foot-pound-force per second to kilojoule per second.
-
Supports power unit conversion between imperial and metric units commonly used in engineering and industry.
-
Provides exact conversion factor based on established definitions.
Examples
-
5 horsepower (550 ft*lbf/s) converts to approximately 3.728499358 kJ/s.
-
10 horsepower (550 ft*lbf/s) converts to approximately 7.456998716 kJ/s.
Common Use Cases
-
Rating engine power for cars, motorcycles, and small machines using horsepower.
-
Specifying power for appliances, motors, and generators in terms of kilojoules per second.
-
Measuring thermal energy transfer in HVAC systems and power generation equipment.
Tips & Best Practices

Use this conversion for comparing mechanical power ratings with metric power standards.
-
Apply the conversion in engineering contexts requiring consistent unit measurements.
-
Recognize that horsepower values may need conversion when working internationally.
Limitations
-
Horsepower (550 ft*lbf/s) is primarily used in regions using imperial units and is not standard everywhere.
-
Conversion may involve minor rounding differences due to decimal precision.
-
Conversion assumes stable measurement conditions and does not factor in efficiency variations.
Frequently Asked Questions
-
What is horsepower (550 ft*lbf/s)?
-
Horsepower (550 ft*lbf/s) is an imperial power unit equal to 550 foot-pound-force per second, defined by James Watt, and measures the rate of work or energy transfer.
-
How does kilojoule per second relate to watts?
-
One kilojoule per second (kJ/s) equals one kilowatt (kW), which is 1,000 watts, representing a metric unit of power.
-
Why convert horsepower to kilojoule per second?
-
Converting allows expressing power output or consumption in metric units, facilitating comparisons between mechanical and electrical power in scientific and engineering settings.
