About Millijoule per cubic metre
The millijoule per cubic metre (mJ/m³) equals 10⁻³ J/m³. Used in radiation physics for describing energy densities of laser pulses in large volumes and in some acoustic energy density contexts. 1 mJ/m³ = 10⁻³ J/m³ = 10³ µJ/m³.
About Kilowatt-hour per cubic metre
The kilowatt-hour per cubic metre (kWh/m³) equals exactly 3.6 × 10⁶ J/m³. Widely used in battery technology and electrical energy storage: Li-ion cells ≈ 200-700 kWh/m³, pumped hydro ≈ 0.27-1.5 Wh/m³. Also used for volumetric electricity price comparisons. 1 kWh/m³ = 3.6 MJ/m³ = 3600 kJ/m³.
