Convert energy density between J/m³, MJ/m³, J/L, Wh/m³, kWh/m³ and Btu/gal.
Energy density expresses the amount of energy stored per unit of volume, relevant in batteries, fuels and thermal storage. The joule per cubic metre (J/m³) is the SI unit; J/L and kWh/m³ are common in practical applications. Select the units and enter a value. For example, 1 MJ/m³ equals 1,000,000 J/m³ or 1,000 J/L.
