L/mil to MPG (UK)

1 liter per mil equals 28.24809363 miles per gallon (imperial).

1 liter per mil = 28.24809363 miles per gallon (imperial)

How to convert liters per mil to miles per gallon (imperial)

Converting liters per mil to miles per gallon (imperial) is not a simple multiplication, so use the formula below.

miles per gallon (imperial) = 28.24809363 ÷ liters per mil

Example: 10 liters per mil = 2.824809363 miles per gallon (imperial).

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).

Mile Per Gallon (imperial) (mpg (UK))

Imperial (British)Current unit

Miles traveled on one imperial gallon (4.546 L). The UK still quotes fuel economy this way, so UK mpg figures are about 20% higher than US ones for the same car.

Britain's gallon is a child of the 1824 reform. It was originally defined as the volume of 10 pounds of distilled water at 62 degrees Fahrenheit, taken as 277.274 cubic inches; an 1889 Order in Council changed the figure to 277.463 cubic inches, and in 1976 the UK adopted the metric definition of exactly 4.54609 litres, after Canada had done so. The gallon used in the United States comes from a different, older wine measure, so the two differ by about 20 percent.

One imperial gallon is about 1.2 US gallons, which means that a car rated at 40 mpg in the UK delivers only about 33 mpg on the US scale. Miles per imperial gallon is still the UK's main fuel-economy unit even though petrol is sold by the litre and selling goods by the imperial gallon is no longer legal in Britain. Some Caribbean territories, such as the Cayman Islands and Grenada, still sell petrol by the imperial gallon, while the UAE, Guyana and Myanmar switched to litres in 2010, 2013 and 2014. When a figure says only mpg, check which gallon is meant.

1 mile per gallon (imperial) = 0.3540061899 kilometers per liter (approximately).
