Kilojoule per cubic meter quick reference
| Kilojoule per cubic meter | Megajoule per cubic meter | BTU per cubic foot | Joule per cubic meter |
|---|---|---|---|
| 1 kJ/m³ | = 0.001 MJ/m³ | ≈ 0.02683919199 BTU/ft³ | = 1000 J/m³ |
| 10 kJ/m³ | = 0.01 MJ/m³ | ≈ 0.2683919199 BTU/ft³ | = 10000 J/m³ |
| 100 kJ/m³ | = 0.1 MJ/m³ | ≈ 2.683919199 BTU/ft³ | = 100000 J/m³ |
| 1000 kJ/m³ | = 1 MJ/m³ | ≈ 26.83919199 BTU/ft³ | = 1000000 J/m³ |
Where the kilojoule per cubic meter fits
The next smaller fuel energy per volume unit is the joule per cubic meter (J/m³). 1 kJ/m³ = 1000 J/m³, and 1 J/m³ = 0.001 kJ/m³.
The next larger fuel energy per volume unit is the BTU per cubic foot (BTU/ft³). 1 kJ/m³ ≈ 0.02683919199 BTU/ft³, and 1 BTU/ft³ ≈ 37.25894581 kJ/m³.
