Kilowatt-hours per cubic meter to megajoules per cubic meter
Type a value in kWh/m³ to get it in MJ/m³ instantly.
129.6MJ/m³
That's 3.3× as energy-dense as natural gas at room pressure, while a lead-acid battery is 2.5× denser. A 50-liter tank of it would hold about 1.8 kWh.
Convert the other way: MJ/m³ to kWh/m³
What it means
How much fits in a liter?
Fuels use the higher heating value; batteries are usable electrical energy per liter of cell. Gases are at atmospheric pressure unless stated.
The math
How to convert kWh/m³ to MJ/m³
To convert kilowatt-hours per cubic meter to megajoules per cubic meter, multiply by 3.6.
Example: 36 kWh/m³ × 3.6 = 129.6 MJ/m³.
In the other direction, 1 MJ/m³ = 0.277778 kWh/m³.
