30 mpg (U.S.) is about 7.84 L/100 km.
Convert vehicle fuel economy between miles per gallon (U.S.) and liters per 100 kilometers. It is designed for quick estimates and everyday problem solving. When a calculation affects a contract, tax filing, medical decision or other high-stakes situation, verify the result with the appropriate professional or authoritative source.
Miles per gallon measures distance traveled for a fixed amount of fuel, so a higher MPG value indicates better fuel economy. Liters per 100 kilometers measures fuel used for a fixed distance, so a lower L/100 km value indicates better fuel economy. Because the two measures are reciprocals, they are converted by dividing the same constant by the input value.
30 MPG (U.S.) is approximately 7.84 L/100 km. A vehicle rated at 8.0 L/100 km is approximately 29.40 MPG (U.S.). Actual fuel consumption can differ because of speed, temperature, terrain, vehicle load, tire pressure and driving conditions.
30 U.S. miles per gallon converts to about 7.84 liters per 100 kilometers; fuel use moves inversely with MPG.
Smaller L/100 km numbers mean better efficiency, whereas larger MPG numbers mean better efficiency.
This uses U.S. gallons, not imperial gallons, and assumes consistent fuel-economy test conditions.
