Megajoules per liter to watt-hours per liter
Type a value in MJ/L to get it in Wh/L instantly.
10,000Wh/L
That's 1.05× as energy-dense as petrol, while diesel is 1.07× denser. A 50-liter tank of it would hold about 500 kWh.
Convert the other way: Wh/L to MJ/L
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 MJ/L to Wh/L
To convert megajoules per liter to watt-hours per liter, multiply by 277.778.
Example: 36 MJ/L × 277.778 = 10,000 Wh/L.
In the other direction, 1 Wh/L = 0.0036 MJ/L.
