Hi,
I have another app where I enter the following when I refuel:
Quantity in Litres
Price in Pence
Distance in miles
it then calculates the MPG (in miles) and the refuel cost.
The point is that the UK petrol stations dispense fuel in litres. However, UK vehicles record distance in miles. So, and this might just be because I am an old fart, people usually calculate their fuel consumption and efficiency in miles per gallon
Example:
Qty: 16.14 Litres
Price: 179.1 Pence per Litre
Trip Distance: 179.1 MILES
Refuel cost (calculated by app and spot on) £22.23
Calculated MPG: 50.45MPG
Hope this helps
