Understanding Distance-Per-Volume vs. Volume-Per-Distance
Most English-speaking nations measure fuel economy as distance traveled per unit of fuel (Miles per Gallon), where higher numbers indicate better efficiency. Continental Europe and much of the world measure consumption as fuel volume required to travel a fixed distance (Liters per 100 Kilometers), where lower numbers represent superior efficiency.
Conversion Formula Matrix
| From | To | Exact Mathematical Formula |
|---|---|---|
| US MPG | L/100km | $\text{L/100km} = 235.215 / \text{MPG}_{\text{US}}$ |
| UK Imperial MPG | L/100km | $\text{L/100km} = 282.481 / \text{MPG}_{\text{UK}}$ |
| US MPG | UK Imperial MPG | $\text{MPG}_{\text{UK}} = \text{MPG}_{\text{US}} \times 1.20095$ |
| L/100km | km/L | $\text{km/L} = 100 / (\text{L/100km})$ |
