1 gallon is about 3.8 liters. 1 mile is about 1.6km.
35 mi/gal = (35 * 1.6km)/gal = (35 * 1.6km)/3.8l
You want liters per kilometer tho, so reciprocal: 3.8l/(1.6km * 35)
To drive 100 km, you need 100 times the fuel => (3.8l*100)/(1.6km * 35) ~ 6.8 l/100km
I’m getting 6.7l/100 km using Google. Not sure what math you’re doing. But keep in mind there are two different gallons, US and Imperial or something. 35 mpg is pretty normal for a gasoline-only car these days (hybrids can do better depending on driving conditions - if they can spend most of their time on battery, for example). Diesel cars aren’t much of a thing in the US, again, especially after the whole Volkswagen cheating thing.
I know there used to be diesel cars in the 80s that would get crazy numbers like 50 mpg (4.7l/100km), and gas-powered cars probably could now, too, but emissions and safety requirements have pretty much killed that.
I really shouldn’t do math in my head…
I looked up the 9ish, but not sure what calculator that was. I do get to 6.7 now too, so that is really not that bad.
I was starting to wonder what kind of cars you guys have that get such incredible fuel economy. :)
Yeah, but it’s 50 years old. 12 was the average, and you really didn’t see anything getting better that 25. That’s on older roads with leaded gas and bias tires.

Sadly, that’s actually on the higher end of the spectrum when it comes to American vehicles

No wonder with all the trucks or SUV
