What Is This Tool?
This tool converts fuel consumption rates from gram/kilowatt/hour (g/kW·h) to gram/horsepower (metric)/hour (g/(metric hp·h)). It helps compare and report specific fuel consumption across different power measurement units used in industries like automotive, marine, and power generation.
How to Use This Tool?
-
Enter the value in gram/kilowatt/hour representing specific fuel consumption
-
Select the conversion to gram/horsepower (metric)/hour
-
Click convert to see the equivalent value in g/(metric hp·h)
-
Use the converted result for engine performance reports or fuel efficiency comparisons
Key Features
-
Converts specific fuel consumption units between g/kW·h and g/(metric hp·h)
-
Supports reporting and performance evaluation of internal combustion engines and turbines
-
Allows comparison of fuel efficiency in various engine and power generation applications
-
Browser-based and easy to use with quick input and output display
Examples
-
10 g/kW·h converts to 7.3549875 g/(metric hp·h)
-
5 g/kW·h converts to 3.67749375 g/(metric hp·h)
Common Use Cases
-
Reporting brake specific fuel consumption (BSFC) values for engines tested on dynamometers
-
Comparing fuel efficiency of marine and stationary engines for benchmarking
-
Optimizing engine tuning and fuel use in powerplants and propulsion systems
-
Converting legacy engine data to SI units for regulatory compliance and analysis
Tips & Best Practices
-
Verify the definition of horsepower used in your region when interpreting results
-
Use this tool for specific fuel consumption measures only, not general mass or energy units
-
Cross-check converted values when comparing legacy and modern engine data for accuracy
-
Apply conversions consistently for performance evaluations across different unit standards
Limitations
-
Based on the metric horsepower definition as 735.49875 watts; differing regional horsepower definitions may affect accuracy
-
Applicable only for specific fuel consumption per unit of power and time, not for general mass or energy conversions

Key Terminology
-
Gram/kilowatt/hour (g/kW·h)
-
A measurement of the amount of fuel mass consumed per kilowatt-hour, expressing specific fuel consumption.
-
Gram/horsepower (metric)/hour (g/(metric hp·h))
-
Mass of fuel consumed per metric horsepower per hour, used to express specific fuel consumption for engines.
-
Brake Specific Fuel Consumption (BSFC)
-
A metric for evaluating fuel efficiency of engines, representing fuel mass consumed per unit power output over time.
