Formule
Fuel economy is distance divided by fuel (mpg, km/L) or fuel per distance (L/100 km). Lower L/100 km and higher mpg are better.
mpg = miles ÷ gallons
L/100 km = liters ÷ km × 100
L/100 km = 235.215 ÷ mpg (US)
Example
- 320 miles on 11.2 gallons = 28.57 mpg.
- That's 8.23 L/100 km or 12.15 km/L.
Questions fréquentes
Why are UK mpg figures higher?
A UK (imperial) gallon is about 20% larger than a US gallon, so the same car gets more miles per UK gallon.
Why does my mileage differ from the official rating?
Driving style, speed, traffic, temperature, tire pressure and load all affect real-world economy.
How can I improve fuel economy?
Drive smoothly, keep tires properly inflated, remove excess weight and roof racks, and moderate highway speed.
