Gas Mileage Calculator

Calculate fuel economy in automobiles in US or Metric units. Calculate vehicle fuel economy in mpg US (miles per US gallon), mpg Imp (miles per Imperial gallon), km/l (kilometers per liter) or fuel consumption in l/100km (liters per 100 kilometers). Equivalent fuel economy/efficiency ratings are converted and shown for all units, mpg US, mpg Imp, km/l and l/100km.
