Grams per kilowatt-hour to grams per horsepower-hour
Type a value in g/kWh to get it in g/hp·h instantly.
149.1g/hp·h
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/hp·h
To convert grams per kilowatt-hour to grams per horsepower-hour, multiply by 0.7457.
Example: 200 g/kWh × 0.7457 = 149.14 g/hp·h.
In the other direction, 1 g/hp·h = 1.34102 g/kWh.
