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 Gigajoule per cubic metre

The gigajoule per cubic metre (GJ/m³) equals exactly 10⁹ J/m³. Used for the energy density of high-energy-density materials and liquefied fuels: LNG ≈ 22.2 GJ/m³, liquid hydrogen ≈ 8.49 GJ/m³, petrol ≈ 34.2 GJ/m³. Also useful for large-scale thermal energy storage reservoirs. 1 GJ/m³ = 10³ MJ/m³ = 10⁹ J/m³.
