What Is This Tool?

This tool converts fuel efficiency from gram per thermochemical calorie (g/cal (th)) to gram per metric horsepower per hour (g/(hp·h)). It helps translate mass-based fuel usage per unit thermal energy into a practical metric for engine fuel consumption relative to power output over time.

How to Use This Tool?

  • Enter the value in gram/calorie (th) [g/cal (th)] you want to convert
  • Choose 'gram/calorie (th) [g/cal (th)]' as the input unit if not pre-selected
  • Select 'gram/horsepower (metric)/hour' as the output unit
  • Click convert to get the result instantly in grams per metric horsepower per hour
  • Use the output to analyze fuel consumption based on engine power performance

Key Features

  • Converts between fuel efficiency mass units related to thermal energy and engine power output
  • Uses a precise conversion factor of 1 g/cal (th) = 632838.31261875 g/(hp·h)
  • Supports analysis for internal combustion and marine engines as well as stationary powerplants
  • Browser-based and easy to use without need for software installation
  • Provides quick numeric conversion suitable for engineering and regulatory applications

Examples

  • Converting 0.002 g/cal (th) yields 1265.68 g/(hp·h)
  • Converting 0.01 g/cal (th) gives 6328.38 g/(hp·h)

Common Use Cases

  • Comparing mass fuel efficiency based on thermal energy consumption
  • Converting fuel efficiency data for engine test cells and dynamometer reports
  • Estimating fuel mass requirements for propulsion and powerplant design
  • Optimizing engine tuning and load scheduling with fuel consumption metrics
  • Translating legacy engine data for compliance and performance analysis

Tips & Best Practices

  • Ensure that the energy units are clearly understood to apply this conversion properly
  • Use consistent units when analyzing engine fuel consumption and performance data
  • Verify conversion results when operating conditions or fuel types vary significantly
  • Apply the tool to compare fuel efficiency across different engines or fuels effectively
  • Incorporate the conversion into regulatory reporting workflows as needed

Limitations

  • Conversion depends on accurate energy equivalence and may not reflect all engine variables
  • Differences in fuel composition and operating conditions can affect practical use
  • The large conversion factor shows that units measure very different scales and contexts
