Unit definitions
What is a mile per US gallon?
Miles per US gallon (mpg) is the fuel-economy measure used in the United States, counting how many miles a vehicle travels on one US gallon (3.785 liters) of fuel. A higher number means better economy. It is the reciprocal of liters-per-100km once gallons and miles are accounted for.
What is a liter per 100 km?
Liters per 100 kilometers (L/100km) is the standard fuel-consumption measure across Europe and most of the world. It states how much fuel a vehicle burns to travel 100 km, so a lower number means a more efficient car — the opposite direction to miles-per-gallon.
Frequently asked questions
What is the formula to convert miles per US gallon to liters per 100 km?
L/100km = 235.21458 ÷ mpg (US). For example, 20 mpg (US) equals 11.761 L/100km.
Why isn't mile per US gallon to liter per 100 km a simple multiplication?
Because one unit measures fuel per distance and the other measures distance per fuel — they are reciprocals. Doubling the mile per US gallon value roughly halves the liter per 100 km value, so the conversion divides rather than multiplies.
