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 Kilojoule per cubic metre
The kilojoule per cubic metre (kJ/m³) equals exactly 1000 J/m³. Common in gas industry and HVAC for expressing the volumetric heating value of fuel gases: natural gas ~35-38 MJ/m³, biogas ~20-25 MJ/m³, hydrogen ~10.8 MJ/m³ (standard conditions). 1 kJ/m³ = 1000 J/m³ = 1 Wh/(277.8 m³).
