Grams per kilowatt-hour to grams per megajoule
Type a value in g/kWh to get it in g/MJ instantly.
55.56g/MJ
That's 1.03× as thirsty as a truck diesel, while a car diesel is 1.15× thirstier. That is a thermal efficiency of about 42.06%.
What it means
How thirsty is that engine?
Efficiency figures assume diesel at 42.8 MJ/kg. Gasoline holds about 44 MJ/kg and hydrogen 120, so the same g/kWh means different efficiencies for each.
The math
How to convert g/kWh to g/MJ
To convert grams per kilowatt-hour to grams per megajoule, multiply by 0.277778.
Example: 200 g/kWh × 0.277778 = 55.5556 g/MJ.
In the other direction, 1 g/MJ = 3.6 g/kWh.
