What Is This Tool?
This tool converts fuel efficiency mass units from gram per kilowatt-hour, which measures fuel consumption rate, to kilojoule per kilogram, which expresses specific energy content. It helps relate fuel consumption metrics to energy-per-mass values used in various engineering applications.
How to Use This Tool?
- Enter the value in gram/kilowatt/hour representing specific fuel consumption
- Select gram/kilowatt/hour as the starting unit and kilojoule/kilogram [kJ/kg] as the target unit
- Click convert to obtain the equivalent energy content per kilogram value
- Use the results to assess fuel efficiency and energy content relationships
- Apply conversion factor of 1 g/kW·h = 3,600,000 kJ/kg for manual calculations
Key Features
- Converts fuel efficiency from gram/kilowatt/hour to kilojoule/kilogram [kJ/kg]
- Based on a fixed conversion factor linking mass consumption to energy content
- Supports applications in automotive, aerospace, marine, and power generation sectors
- Provides straightforward input and output for quick calculations
- Includes practical examples to illustrate conversion steps
Examples
- Convert 2 g/kW·h: 2 × 3,600,000 = 7,200,000 kJ/kg
- Convert 0.5 g/kW·h: 0.5 × 3,600,000 = 1,800,000 kJ/kg
Common Use Cases
- Reporting brake specific fuel consumption (BSFC) for engines and turbines
- Specifying fuel consumption for power plants and stationary generators
- Comparing energy density and fuel efficiency in marine and industrial engines
- Assessing calorific value of fuels for emissions and selection
- Analyzing specific energy in aerospace propulsion and power generation
Tips & Best Practices
- Confirm consistency in fuel properties and measurement conditions during conversion
- Use this conversion to relate consumption rates to energy content but consider context
- Apply the fixed conversion rate carefully when comparing different fuels or engines
- Double-check unit selections to ensure accurate input and output
- Utilize examples as a guide for performing manual calculations
Limitations
- Assumes standard energy unit definitions and consistent fuel characteristics
- Fuel composition variations may impact conversion accuracy
- Gram/kilowatt/hour measures consumption rate, whereas kilojoule/kilogram measures energy content, requiring contextual interpretation
- Direct conversion may not fully reflect complex thermodynamic properties
