About Watt-hour per cubic metre

The watt-hour per cubic metre (Wh/m³) equals exactly 3600 J/m³. Convenient for energy storage systems - battery packs, flywheels, and compressed-air storage - where energy is usually expressed in watt-hours per physical volume. 1 Wh/m³ = 3600 J/m³ = 3.6 kJ/m³.

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.
