What it means
How far on one tank?
Range assumes a 50-liter tank. US and UK gallons differ, so always check which mpg a figure means.
The math
How to convert mpg (US) to L/100 km
These units run in opposite directions, so the conversion divides instead of multiplying: L/100 km = 235.215 ÷ mpg (US), and km/L = 100 ÷ L/100 km.
Example: 30 mpg (US) = 7.84049 L/100 km.
