What Is This Tool?
This tool allows you to convert fuel efficiency volume measurements from gallon (US)/horsepower (metric)-hour, which represents fuel consumption per mechanical power output, to Btu (th)/cubic foot, a unit expressing thermal energy content per volume of fuel.
How to Use This Tool?
-
Enter the value in gallon (US)/horsepower (metric)-hour representing fuel consumption
-
Select gallon (US)/horsepower (metric)-hour as the input unit
-
Choose Btu (th)/cubic foot as the output unit
-
Click convert to obtain the energy content per volume in Btu (th)/cubic foot
Key Features
-
Converts volumetric specific fuel consumption to thermal energy content per volume
-
Includes units relevant for engines, generators, and marine propulsion systems
-
Supports comparisons of fuel efficiency and calorific values across different units
-
Browser-based, easy-to-use interface for quick conversions
Examples
-
2 gallon (US)/horsepower (metric)-hour = 2 × 18785.868876096 = 37571.738 Btu (th)/cubic foot
-
0.5 gallon (US)/horsepower (metric)-hour = 0.5 × 18785.868876096 = 9392.934 Btu (th)/cubic foot
Common Use Cases
-
Specifying fuel consumption of engines, generators, or marine propulsion systems rated in metric horsepower
-
Comparing efficiency of engines or machines by converting to other specific fuel consumption units
-
Estimating fuel usage and planning fuel storage requirements during operations
-
Converting natural gas volumes to energy for billing and reporting purposes
-
Sizing and analyzing performance of boilers, furnaces, and burners
-
Assessing gas quality and calorific value in pipelines and fuel procurement
Tips & Best Practices
-
Ensure consistent fuel quality to maintain accuracy in conversions
-
Consider the impact of temperature and pressure on volumetric measurements
-
Use this tool for initial estimates and verify with local standards when necessary
-
Compare fuel efficiency and calorific values only when using standardized units
Limitations
-
Conversion assumes uniform fuel quality and composition; variations may affect results
-
Measurement condition differences like temperature and pressure can introduce errors
-
Certain applications might require adjustments based on regional standards or fuel types
Frequently Asked Questions
