    Miles per gallon to liters per 100 km formula

    L/100km = 235.215 ÷ mpg
    1. Take the fuel economy in US miles per gallon.
    2. Divide 235.215 by it. For UK mpg divide 282.481 instead.

    Example: 235.215 ÷ 30 mpg = 7.84049 L/100km.

    Reverse formula: mpg = 235.215 ÷ L/100km. Example: 235.215 ÷ 8 = 29.4 mpg.

    Because one unit is distance per fuel and the other fuel per distance, the scale is inverted: doubling mpg halves L/100km.

    About miles per gallon and liters per 100 km

    Miles per gallon (mpg). Miles per gallon measures how far a vehicle travels on one gallon of fuel: higher is better. US and UK mpg differ because the gallons differ.

    Liters per 100 km (L/100km). Liters per 100 kilometers measures how much fuel a vehicle uses to cover 100 km: lower is better. It is the standard in Europe, Australia and Canada.

    Frequently asked questions

    How do you convert mpg to L/100km?

    Divide 235.215 by the US mpg figure (or 282.481 by the UK mpg figure). For example, 30 US mpg = 235.215 ÷ 30 = 7.84 L/100km.

    What is 40 mpg in liters per 100 km?

    40 US mpg is 5.88 L/100km. 40 UK mpg is 7.06 L/100km.

    Why is the conversion not a simple multiplication?

    mpg is distance per amount of fuel, while L/100km is fuel per distance. One is the reciprocal of the other, so you divide a constant by the value.

    Are US and UK mpg different?

    Yes. A UK (imperial) gallon is about 20% larger than a US gallon, so the same car shows a higher number in UK mpg: 30 US mpg ≈ 36 UK mpg. Choose the right type above.

    What is 35 miles per gallon in liters per 100 km?

    35 mpg is 6.72042 L/100km (compact car). This uses US gallons; switch to UK mpg above if needed.

    Is this converter free and private?

    Yes. It is free with no sign-up, and every calculation runs in your browser, so nothing you type is sent to a server.
