About International table BTU per cubic foot

The international table BTU per cubic foot (BTU(IT)/ft³) equals 1055.05585262 J / (0.3048)³ m³ ≈ 37258.95 J/m³. Standard in US and Canadian gas industry for expressing the gross calorific value of natural gas as distributed (pipeline quality gas ≈ 1000 BTU/ft³). 1 BTU(IT)/ft³ ≈ 37.26 kJ/m³ ≈ 10.35 Wh/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.
