Will the ScanGaugeII display in metric?
Yes, the units of measure can be independently selected between Miles/Km, Gallons/Liters, Celcius/Fahrenheit, and PSI/KPA. If you choose Km and Liters, fuel economy is reported as liters/100Km (LHK). If you use Imperial Gallons when you do the calibration, fuel will then be adjusted to use Imperial Gallons.
