Quick answer
This converts energy density: energy per unit volume of fuel. The SI unit is joules per cubic metre: one megajoule per cubic metre is a million and one BTU per cubic foot is 37,258.9 J/m³. Volume matters more than mass wherever tank space rather than weight is the binding constraint, which is why compressed gases are compared this way.
| Joule per cubic metre (J/m³) | 1 |
| Kilojoule per cubic metre (kJ/m³) | 0.001 |
| Megajoule per cubic metre (MJ/m³) | 0.000001 |
| BTU (IT) per cubic foot (BTU/ft³) | 0.00002683919199 |
About the Fuel Heating Value - Volume Converter
Fuel heating value by volume measures the energy released per unit of fuel volume, such as joules per cubic metre or BTU per cubic foot. It is the energy density of a fuel.
It is used when comparing fuels that are stored or metered by volume, including gases and liquid fuels.
Frequently Asked Questions
What is energy density?
⌄
Energy density is the amount of energy stored per unit of volume, exactly what this converter measures.
What is the SI unit?
⌄
The SI unit is the joule per cubic metre (J/m³).
When is volume-based efficiency preferred?
⌄
It is preferred when fuel is sold or stored by volume, since tank size and pumping depend on volume rather than mass.
