Fuel Consumption Conversion
The following utility will allow you to convert between fuel consumption expressed in one unit to another unit
Fuel consumption is generally expressed as MPG (Miles Per Gallon) but nowadays the expression litres per 100km (L/100km) is also becoming popular.
The information in the table below provides a method of converting from MPG to the listed expression.
|Scheme||Convert to||Multiply MPG by|
|U.S. gallon||Metres per Cubic meter (m/m³)||425 143.7|
|U.S. gallon||Kilometre per litre (km/L)||0.425 143 7|
|U.K. & Canada gallon||Metres per Cubic meter (m/m³)||354 006.2|
|U.K. & Canada gallon||Kilometre per litre (km/L)||0.354 006 2|
To calculate Litres per one hundred kilometres (L/100km) first calculate the Kilometres per Litre (km/L) using the above table then divide 100 by this km/litre value.
For example you have a truck that returns 25mpg (based on U.S. gallons) and you wish to compare that figure with another truck which has a fuel consumption quoted in litres per 100km. 1st calculate the kilometres per litre
km/L = 25 multiplied by 0.425 This equals 10.625 kilometres per litre.
2nd calculate the litres per 100km
L/100km = 100 divided by 10.625 This equals 9.412 litres per 100 kilometres(L/100km)
