Convert energy density units including joules per cubic meter, kilojoules per cubic meter, megajoules per cubic meter, joules per liter, watt-hours per liter, BTU per cubic foot, calories per cubic centimeter, and more.
Joules per cubic meter to joules per liter:
1 J/m³ = 0.001 J/L
Watt-hours per liter to joules per cubic meter:
1 Wh/L = 3,600,000 J/m³
Megajoules per cubic meter to joules per cubic meter:
1 MJ/m³ = 1,000,000 J/m³
BTU per cubic foot to joules per cubic meter:
1 BTU/ft³ = 37,258.9 J/m³
Energy density conversions are useful for batteries, fuels, natural gas, compressed air, thermal storage, energy systems, materials testing, combustion calculations, and volume-based energy comparisons.
Use this converter when comparing SI, U.S. customary, battery, fuel, thermal, and volume-based energy density units.
Your result shows the entered energy density converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering, battery, fuel, and thermal calculations, make sure the energy density unit matches your data sheet, formula, model, or design reference.
Energy density is the amount of energy stored or contained per unit volume.
The common SI unit of volumetric energy density is joules per cubic meter, abbreviated as J/m³.
Yes. Watt-hours per liter is commonly used for batteries and energy storage because it compares stored energy by volume.
One watt-hour per liter equals 3,600,000 joules per cubic meter.
This converter is designed for energy density magnitude conversions, so it uses non-negative values.
