can I change site units?
 

I am in Canada and buy fuel in liters. Any way that I can enter my info in liters and kms? Kinda pointless to join a site like this if I have to maually convert my data first...thanks.

Welcome to ecomodder.

Being from the old continent, I feel your pain, but there's no way to enter liters and kilometers in the ecomodder garage directly.

You can use the forum tools to convert units though:
Fuel economy conversions / calculator - EcoModder.com


Onlineconversions.com have a multitude of unit conversions.
I most often use these to translate the units.
Like mileage :
Online Conversion - Fuel Consumption Conversion


I keep a fuel record at
MPG and Cost Calculator and Tracker - Spritmonitor.de
which allows metric and US / Imp Gallons.
While I keep my record in metric, I can get some code to show MPG on a forum - see my signature.
