Conversion Formula
Wh/m³ = kWh/m³ × 1000
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.
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.
