What Is This Tool?
This tool converts fuel-specific consumption expressed in pound/horsepower/hour to the SI unit of specific energy, joule per kilogram (J/kg). It helps users compare engine fuel efficiency and energy content of different fuels by translating mass-specific consumption into energy per mass.
How to Use This Tool?
- Enter the value in pound/horsepower/hour you want to convert
- Select pound/horsepower/hour as the input unit
- Select joule/kilogram [J/kg] as the output unit
- Click convert to see the equivalent energy per mass in joules per kilogram
Key Features
- Converts pound/horsepower/hour to joule/kilogram [J/kg]
- Supports fuel efficiency mass unit conversions for automotive, aerospace, and industrial engines
- Based on standardized unit definitions for accurate energy content comparisons
- Browser-based and easy-to-use with instant results
- Includes example conversions for quick understanding
Examples
- 2 pound/horsepower/hour equals 11836705.0032 joule/kilogram [J/kg]
- 0.5 pound/horsepower/hour equals 2959176.2508 joule/kilogram [J/kg]
Common Use Cases
- Reporting brake specific fuel consumption for piston and automotive engines
- Estimating fuel burn and range for aircraft gas-turbine or turboprop engines
- Evaluating fuel use in industrial generators and marine engines
- Comparing specific energy content of fuels such as aviation fuel and diesel
- Assessing battery specific energy in electric vehicles and electronics
