About Megajoule per cubic metre
The megajoule per cubic metre (MJ/m³) equals exactly 10⁶ J/m³. The practical SI unit for fuel energy density: natural gas ≈ 35-40 MJ/m³, hydrogen (liquid) ≈ 8490 MJ/m³, diesel ≈ 34,200 MJ/m³. Numerically equal to kJ/L and widely used in fuel standards and energy audits. 1 MJ/m³ = 10⁶ J/m³ = 1 kJ/L.
About Megawatt-hour per cubic metre
The megawatt-hour per cubic metre (MWh/m³) equals exactly 3.6 × 10⁹ J/m³. Used in large-scale energy storage infrastructure - pumped hydro, grid-scale battery installations, and thermal storage plants. Petrol ≈ 9.5 MWh/m³, LNG ≈ 6.2 MWh/m³, Li-ion pack ≈ 0.56 MWh/m³. 1 MWh/m³ = 3.6 GJ/m³ = 3600 MJ/m³.
