About Kilojoule per litre

The kilojoule per litre (kJ/L) equals exactly 10⁶ J/m³ = 1 MJ/m³ (since 1 L = 10⁻³ m³). The preferred notation in fuel chemistry and food science for volumetric energy content. Gasoline ≈ 34.2 MJ/L, diesel ≈ 35.8 MJ/L, ethanol ≈ 23.4 MJ/L, LPG ≈ 25.5 MJ/L. 1 kJ/L = 1 MJ/m³ = 10⁶ J/m³.

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.
