Fuel Consumption Calculator

European fuel economy is measured in liters per 100 kilometers: fill the tank, drive, refill, and divide the liters used by the distance, times 100. Using 45 liters over 620 km gives 7.26 L/100km.

Lower is better — small cars manage 5–6 L/100km, SUVs often exceed 8. Tracking real consumption over several tanks reveals the effect of driving style, tire pressure and load. Multiply the result by your fuel price to estimate cost per 100 km, and see the liters to gallons converter for US MPG comparisons.
