MPG Conversion

[AshD93]

Can someone just confirm this is right for me as my numbers are a bit odd?

VCDS logged my Audi's Speed (km/h) and Consumption (l/h).

To convert this into MPG I did...

Speed (km/h) / Consumption (l/h) = (km/l)

(km/l) * (1KM in Miles = 0.621371192)/(1 Liter in Gallon = 0.219969) = m/g or MPG

Or have I made a silly mistake (which is normal for me).

Thanks in advance.

Sorry, I should have added I am after instantaneous and not average.

I'll go through my sheets again.

Thanks everyone!
