What Is This Tool?
This unit converter transforms fuel efficiency mass units from pound per horsepower-hour, which measures fuel mass consumed per mechanical power over time, to pound per Btu (thermal), indicating fuel mass used per thermal energy output.
How to Use This Tool?
- Enter the value in pound per horsepower-hour.
- Select the source unit pound/horsepower/hour and the target unit pound/Btu (th).
- Click the convert button to get the equivalent value in lb/Btu (th).
- Interpret the result for evaluating fuel consumption in thermal energy contexts.
Key Features
- Converts between pound/horsepower/hour and pound/Btu (th) units accurately.
- Supports fuel efficiency analysis in automotive, aviation, marine, and industrial engines.
- Facilitates comparison of mechanical power-based fuel consumption to thermal energy terms.
- Browser-based and easy to use with simple input and output display.
- Includes example conversions to illustrate practical use.
Examples
- 10 pound/horsepower/hour equals 0.003927519 pound/Btu (th).
- 50 pound/horsepower/hour converts to 0.019637595 pound/Btu (th).
Common Use Cases
- Comparing brake specific fuel consumption in automotive and piston engines.
- Estimating fuel burn and range for gas turbines or turboprop aircraft engines.
- Evaluating fuel use of marine engines and industrial generators during performance testing.
- Calculating pounds of fuel per Btu output for boiler and furnace design.
