No you can, tell us what you are getting

MPG is confusing because there are two of them in common use... in USA they use MPG but USA gallons (3,78 litre) and in UK they say MPG but it is UK gallons (4,55 L)

The rest of us that think in L / 100 km is much better

Conversion to SI units

Most countries other than the US and UK use the SI (aka metric) units litre (0.22 Imperial gallon or 0.264 US liquid gallon) and km (0,621 statute miles). These can be combined to either km/L (efficiency) or L/100km (consumption). The UK is a special case in this respect, as distances are measured in miles but fuel is sold by the litre. As a result, both MPG and L/100km are usually quoted for any given vehicle, although the general public almost exclusively use miles-per-gallon.

For US liquid gallons:

* 1 km = 0.621 Mile
* 1 Mile = 1.609 km
* 1 Gallon = 3.79 Litre
* 1 Litre = 0.264 Gallon

* 1 km/L = 0.621M/0.264G = 2.35 MPG
* 1 MPG = 1.609km/3.79L = 0.425 km/L
* 1 MPG ~ 2.35 L/km

[don't forget: MPG can't be equal to L/km the same as km/L can't be equal to L/km. So it can be only said, that efficiency is (vers)proportional to consumption! It means that 1 MPG ~ 2.35 L/km, but 1 GPM = 2.35 L/km ]

* 1 MPG ~ 235 L/100km =>10 MPG ~ 23.5 L/100km; 20 MPG ~ 11.75 L/100km; 30 MPG ~ 7.83 L/100km etc...


For Imperial gallons (UK): if 1 Litre = 0.22 Gallon then

* 1 km/L = 2.8248 MPG
* 1 MPG = 0.354 km/L
* 1 MPG ~ 282.4809 L/100km
Usually European cars that we see here in North America are pretty thirsty... no Fiats for us (anymore)

Anyway I think European highway driving probably burns more than American style even with a big V8, in USA they do not like it when you drive 150 km/h
