Fuel economy conversions

The charts below show conversions for the most common units related to fuel economy. Whilst the majority of the world measures fuel economy in Liters Per 100km, the UK still uses the imperial Miles Per Gallon (MPG). MPG is also sometimes referenced in the United States. However, it's worth remembering that the US gallon is smaller than the UK gallon, meaning MPG measurements for the US unit and the imperial unit are different.
