customise individual settings
 

Entering data has 2 options imperial or metric. In the UK because of european rules fuel is sold and priced in litres. The cars use miles per gallon. After i fill up i have to convert my volume and price from litres to gallons to get a miles per gallon before i enter data.
Is it possible to customise each category? If i want to set volume as litres, price per litre, distance in miles? Or any variation ie volume gallons, price per litre, distance in km.

There is an option to fuel up using litres, set the price per litre, and calculate the MPG's. Im from the UK, thats what ive done and it works fine. You have to edit your fuel up settings.
