Frequently Asked Questions
What is volume-based fuel efficiency?
Volume-based fuel efficiency measures energy content or consumption per unit volume (like J/m³ or BTU/ft³), as opposed to mass-based measurements (J/kg). It’s particularly useful when dealing with gases or liquids where volume measurements are more practical than mass.
When would I use J/m³ vs BTU/ft³?
J/m³ is standard in scientific and international contexts, while BTU/ft³ is commonly used in American engineering applications, especially for natural gas. The choice depends on your industry standards and regional practices.
What are typical values for different fuels?
Gasoline: ~32 MJ/L, Diesel: ~36 MJ/L, Natural gas: ~38 MJ/m³ (varies with pressure), Hydrogen: ~10.8 MJ/m³ at STP. These values can vary based on composition and conditions.
