Fuel economy is usually expressed in the amount of fuel used per unit distance for example, There was an error working with the wiki: Code[1]s per 100 There was an error working with the wiki: Code[2]s (L/100 km). In this case, the lower the value, the more economic a vehicle is (the less fuel it needs to travel a certain distance)
The formula for converting miles per US gallon (3.785 L) to L/100 km is \frac{235.2}{x}, where x is the miles per gallon number. For miles per Imperial gallon (4.546 L) the formula is \frac{282.5}{x}.
In Europe, the two standard measuring cycles for "L/100 km" value are There was an error working with the wiki: Code[3] travel at 90 km/h and rush hour city traffic. A reasonably modern European There was an error working with the wiki: Code[4] may manage motorway travel at 5 L/100 km (47 mpg US) or 6.5 L/100 km in city traffic (36 mpg US), with PowerPedia:carbon dioxide emissions of around 140 g/km.
I.e. an average There was an error working with the wiki: Code[5]n There was an error working with the wiki: Code[6] travels 9 L/100 km highway, 11 L/100 km city
