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 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.
