Thermal efficiency to grams per kilowatt-hour
Type a value in % to get it in g/kWh instantly.
42.06g/kWh
Nothing on our list is smaller: a large marine diesel is 3.9× thirstier. That is a thermal efficiency of about 200%.
Convert the other way: g/kWh to %
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 % to g/kWh
Fuel consumption and efficiency are reciprocals through the fuel’s energy: efficiency % = 360,000 ÷ (42.8 × g/kWh), taking diesel at 42.8 MJ/kg.
Example: 200 % = 42.0561 g/kWh.
