Understanding Fuel Economy Units
MPG (Miles per Gallon): Distance traveled per unit of fuel
L/100km: Fuel consumed per 100 kilometers (lower is better)
km/L: Distance per liter (higher is better)
US vs UK Gallons: US gallon = 3.785L, UK gallon = 4.546L
Inverse Relationship: Higher MPG = Lower L/100km
Global Standards: Most countries use L/100km

About This Conversion
Liters per 100 km to US miles per gallon converts a European or Asian efficiency figure into the number US buyers compare cars by. Divide 235.2145833 by the L/100km value.
The inversion flips which end of the scale is crowded. Between 4 and 6 L/100km, a range covering most modern small cars, the MPG figures spread from 59 to 39, a twenty-point gap. Between 15 and 17, the MPG figures differ by only two. Small differences in L/100km at the efficient end look dramatic in MPG.
