L/mil to L/100 Km

1 liter per mil equals 10 liters per 100 kilometers exactly.

How to convert liters per mil to liters per 100 kilometers

To convert liters per mil to liters per 100 kilometers, multiply the number of liters per mil by 10. This factor is exact. To go the other way, multiply liters per 100 kilometers by 0.1.

liters per 100 kilometers = liters per mil × 10

Example: 10 liters per mil = 100 liters per 100 kilometers.

Miles per gallon rises as a car gets more efficient, while liters per 100 km falls. The conversion between them is a reciprocal (for US mpg: L/100 km = 235.215 ÷ mpg).

About these units

Liter Per Mil (L/mil)

ScandinavianTraditional unit (still used in some regions)

Liters used per 10 km (one Scandinavian 'mil'). Swedish and Norwegian drivers quote fuel use in liters per mil.

Fuel economy in Sweden and Norway is traditionally given as the number of liters burned per mil, the Scandinavian unit of 10 kilometers. That makes it a cousin of the European liters per 100 kilometers figure, just one tenth as large: 0.6 liters per mil is the same as 6 liters per 100 kilometers.

Like consumption figures elsewhere, it counts fuel per distance, so a lower number means a thriftier car. This is the reverse of kilometers per liter or miles per gallon, which count distance per fuel, so a conversion has to invert the value rather than scale it.

The unit survives because the mil itself survives in everyday Scandinavian speech, even though kilometers appear on road signs. Writers there still use it in casual talk about cars, alongside odometer readings quoted in mil.

1 liter per mil = 10 kilometers per liter (exactly).

Liter Per 100 Kilometers (L/100 km)

Metric (SI)Current unit

Fuel used to travel 100 kilometers. The standard fuel-economy unit in Europe, Canada, Australia and China; lower is better.

Where miles per gallon asks how far you go, litres per 100 km asks how much you burn. Consumption is the reciprocal of economy, so it behaves linearly: if two cars each drive 100 km, the one that uses 8 litres instead of 10 saves exactly 2 litres, whatever the starting point. The sources I found do not name an inventor or date for the unit, but it is the standard in much of Europe, Africa, Australia, New Zealand, Canada and China.

Lower is better, which surprises people used to mpg. The relationship between the two scales is a reciprocal: for US mpg, L/100 km equals 235.215 divided by mpg. The Smart Fortwo cdi at about 3.4 L/100 km works out to roughly 69 mpg (US), while a full-size SUV in the US averages around 16 mpg on the highway, which is about 14.7 L/100 km. The US EPA introduced gallons per 100 miles, which carries the same logic, to counter the MPG illusion and make comparisons fairer.

1 liter per 100 kilometers = 100 kilometers per liter (exactly).
