Hey Boris,
I couldn`t find it in there either, but I have figured out the `factor` for you. Take your Kms driven divided by Litres consumed and multiply that result by 2.825, and voila, there is your MPG!
So let`s see if my high school algebra memory is intact:
K (Kms driven) / L (Litres consumed) x 2.825 = m (MPG)
How`s that for service!
Now if you could figure out how to enter that into the Conversion Tool as a `custom calculation` we`ll all have it...
