Fuel Consumption Conversion Calculator

This calculator converts between various measures of fuel consumption:

• Litres per 100km - the European standard.
• Miles per Imperial Gallon - the UK standard.
• Miles per US Gallon - the standard in the USA.

Note

There are 1.200949857 US gallons to 1 Imperial (UK) gallon (US gallons are smaller). Therefore 20 miles per US gallon (less fuel) is more economical than 20 miles per imperial (UK) gallon (more fuel).
