Fuel economy
29.40182288 US mpg
Consumption8 L/100 km
Distance per liter12.5 km/L
Imperial mpg35.310117
How this was calculated
L/100 km = liters consumed ÷ kilometers traveled × 100.
Trip estimates do not include tolls, parking or vehicle maintenance.
Method
Consumption = fuel liters ÷ kilometers × 100. US mpg = 235.214583 ÷ consumption. Distance and fuel are converted to metric before calculating.
Worked example
500 km using 40 L gives 8 L/100 km, 12.5 km/L and approximately 29.401823 US mpg.
Assumptions and limits
For a tank-to-tank measurement, fill to the same level, track distance, then use the fuel added at the next fill. US and imperial gallons differ; use the unit on your fuel measurement.
