Here is another good site for conversions (you also can use it as a dictionary): http://dict.tu-chemnitz.de/doc/calc.de.html



You can reset the average display whenever you want. If you did it, there will be up and down on the first few miles but then it will come to a pretty stable value. But you also can select "Momentanverbrauch" that displays your currently mpg and probably this is what you mean. Put the pedal to the metal and the display makes you wanna cry, lift the throttle and you can even see 45 mpg or so. But this display is rather useless.
The DIC of the CTS makes it possible to switch between mpg and L/100 km, mph and km/h, °F and °C, remaining miles/km of fuel etc.

UK use miles.

No, the British still have their own measures. Miles, yards, pounds, etc.

Anyways, until the early 70ies they even weight in "stones". But this is not common any more.

I thought UK was metric too? They use kilometers instead of miles right?

My link was from an Australian site, it seems that they use UK gallon, so not very useful finally...

Thanks BlackIce, that link for conversion is nice And it gives both UK & US measures, which can be useful.

Taxiguy >> I guess that European who give measures in MPG are people from UK (maybe Ireland too?), as all the "continental" Europe use metric system for most of the things (except wheel rims and PC screens, I do not know why :D)

This site will do the calculations for you (they have many other calculators too, very useful).
I may measure everything else in metric, but L/100Km doesn't really mean anything to me. Most of the auto journalism I read is American (or British), so I only have a sense of what constitutes good or bad fuel consumption in MPG, L/100Km is just a number to me.
Thanks for the table, antp, I can remember 7L/100Km=40MPG and 35=8, it'll give me a better idea about what the metric figures mean.

uff, I was off by one gallon ...

Link does not work for me.

A question though, I have heard some European members on this site refer to their cars in MPG format. Is this format also used alongside the L/100km format in some countries?

I have that page: http://www.4wdworld.com.au/tipstricks/fuelconv.htm
But it does not give the same result as what I used in my message on the page 1 of this topic. I should remake the calculations manually to see what is right.
When the car does not move, you cannot get a consumtion per km, you can only get a consumtion per hour (usually 1L/h)

How do you convert that measurement into MPG, antp? I would like to know how to do it so when people say their mileage in L/100km I can do the conversion myself and it'll be easier for me to understand

Also a question for Germaneon. Does the mileage rating display in your car vary wildly depending on how your are currently driving, or is it an overall average that stays relatively constant? I ask this becuase I have heard stories of these kind of gauges going down to 3 or 4 MPG when you floor it after a stoplight, and going up to infinty when you take your foot off the accelerator
