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 Joule per cubic metre

The joule per cubic metre (J/m³) is the SI coherent unit for energy density (and equivalently, pressure). It covers a wide range from gas combustion (natural gas ~38 MJ/m³) down to small reaction energies. Numerically equal to the pascal (Pa = N/m² = J/m³). Referenced in ISO 31-4. 1 J/m³ = 10⁻³ kJ/m³ = 1 Pa.
