It can be confusing in the UK where economy is usually quoted in mpg whilst petrol is sold in litres.
Experts find key to saving fuel: say gallons per mile

#22I couldn't find one listing of a gallons per mile in the article.

Is that correct for what they are looking for? My car gets .05 gallons per mile! Wait the structure on that sentence is wrong isn't it?
Re: Experts find key to saving fuel: say gallons per mile
#23If you cross the pond often, it's useful to remember the following: x mpg * y l/100km = 240 (or more exactly 235 and change, but 240 has more divisors and is easier to manipulate). Illustrated: 10 mpg = 24 l/100km 20 mpg = 12 l/100km 24 mpg = 10 l/100km 30 mpg = 8 l/100km 40 mpg = 6 l/100km 60 mph = 4 l/100km Small cars in EU are i the 4-6 l/100km range, or between 40-60 mpg. Sedans are typically between 8-12 l/100km…
My brain's frazzled. Are you using US gallons or Imperial gallons in those calculations? I'd suggest they go a step further though. The first thing I do when looking for a new car is convert the mpg figures into pence per mile.
I used US gallons.

They corrected for this in the tests:
> the tests were repeated using gallons per 100 miles
You could also say "aught-5 gallons per mile," where the decimal is placed by convention. Though then you run into trouble with the .009 gpm cars...

#25I still can't wrap my head around celsius. Is 20 celsius hot? Is 25 hot? I'm not sure. I'd have to convert it to fahrenheit in order to get a feel. Same thing. I know that 20 mpg is somewhat bad, 30 mpg is somewhat good. How about... 0.05 gallons per mile? I'd have to divide it first. This is the reason why grocery stores sometimes advertise prices at 4 dollars per 9 units, and similar. They know people can't work ou…
But like everything, if you use it for a little while you get an intuitive sense for the numbers.
I used to struggle with celsius as well, but then I lived in Spain for a while. Once I stopped converting to Fahrenheit all the time and just tried to associate the numbers with days that I remember, I got where I know that 20 is fresh, 25 is warm, 30 is getting toasty, and 42 is a smokin' hot summer day in Sevilla.

If they did that then the figures would change daily and be different for each market in which the car were sold.
if it could be done in a way you could see something updated a week, would be interesting - maybe would make people think twice before a longer trip (would work with me).

#27My car shows me this on its onboard computer. It gives me instantaneous and averaged litres per 100 kilometres.

Actually I think the Imperial system is better in this case. I find it easier to remember a number which is an integer in the 20-40 range than a real between 5 and 10.
I find that in my mind, most of the relevant numbers tend to get rounded up to "a bit less than ten" anyway.

In Germany you usually talk about how many liters it takes to drive 100 km. And you get numbers of around 5 to 10 (or higher). Even the article says: "When the tests were repeated using gallons per 100 miles, the volunteers correctly picked the greenest option from those available."
Yeah, as the Verizon reps made stunningly obvious[1], the average person struggles with small decimals, but making it a figure like gallons per hundred miles (or liters per 100 km like I have seen in Europe) would make it easier. I heard a similar story to this on NPR the other day. It pointed out that the EPA already gives it's efficiency ratings in gallons per mile, which are then converted back to miles per gallon…
Actually, the window stickers on new cars (at least in this state) do have a "total estimated annual fuel cost", don't they?

Only for you - and only for the current state of efficencies.
