About Kilowatt-hour per cubic metre
The kilowatt-hour per cubic metre (kWh/m³) equals exactly 3.6 × 10⁶ J/m³. Widely used in battery technology and electrical energy storage: Li-ion cells ≈ 200-700 kWh/m³, pumped hydro ≈ 0.27-1.5 Wh/m³. Also used for volumetric electricity price comparisons. 1 kWh/m³ = 3.6 MJ/m³ = 3600 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.
