What Is This Tool?

This converter changes units of fuel efficiency mass from gram per metric horsepower per hour (g/(hp·h)) to pound per British thermal unit (thermal) [lb/Btu (th)]. It helps translate engine-specific fuel consumption rates expressed per unit power and time into mass-based fuel consumption per unit energy.

How to Use This Tool?

  • Enter the fuel consumption value in gram/horsepower (metric)/hour
  • Select pound/Btu (th) [lb/Btu (th)] as the target unit
  • Initiate the conversion to see the equivalent value
  • Use the result to compare or analyze fuel efficiency in thermal units

Key Features

  • Converts specific fuel consumption from g/(metric hp·h) to lb/Btu (th)
  • Supports analysis of engine brake specific fuel consumption (BSFC)
  • Useful for thermal system and fuel efficiency evaluations
  • Browser-based and easy to use without special software
  • Facilitates consistent comparisons across different unit systems

Examples

  • 100 gram/horsepower (metric)/hour converts to approximately 8.7788e-5 pound/Btu (th)
  • 500 gram/horsepower (metric)/hour converts to approximately 4.3894e-4 pound/Btu (th)

Common Use Cases

  • Reporting and comparing BSFC on engine test cells and dynamometer reports for internal combustion, marine, and stationary engines
  • Optimizing engine tuning and fuel-efficiency trade-offs in powerplants or propulsion systems
  • Specifying boiler or furnace fuel consumption in pounds per Btu of heat output for design and performance purposes
  • Comparing fuels by mass-based energy content when selecting fuel for industrial burners and heaters
  • Calculating fuel mass flow to meet thermal power output targets in combustion system sizing and emissions estimation

Tips & Best Practices

  • Ensure steady-state operating conditions for valid conversions
  • Interpret results contextually since the units measure different physical quantities
  • Use this conversion to enable consistent comparisons across units and measurement bases
  • Apply conversions carefully when working with varying fuel compositions or heating values

Limitations

  • Assumes steady-state conditions without accounting for transient engine behavior
  • Does not consider fuel composition differences or heating value variations affecting mass-based consumption accuracy
  • Represents different physical quantities requiring careful interpretation when converting

Frequently Asked Questions

What is gram/horsepower (metric)/hour used for?
It is a unit expressing specific fuel consumption, indicating the mass in grams of fuel consumed while producing one metric horsepower for one hour, commonly used in engine testing and analysis.

Why convert gram/horsepower (metric)/hour to pound/Btu (th)?
Converting enables comparing and evaluating fuel efficiency across different systems by translating power/time-based consumption into mass per energy unit.

Can this conversion be used for transient engine conditions?
No, the conversion assumes steady-state operating conditions and does not account for transient behaviors.

Key Terminology

gram/horsepower (metric)/hour
A specific fuel consumption unit measuring grams of fuel burned per metric horsepower generated in one hour.
pound/Btu (th) [lb/Btu (th)]
A fuel consumption unit representing pounds of fuel required to generate one British thermal unit (thermal) of heat.
Brake Specific Fuel Consumption (BSFC)
A measure of fuel efficiency indicating fuel mass consumption per unit power output over time.
