Does the ScanGauge II support metric units?
Yes, the units of measure can be independently selected between Miles/Km, Gallons/Liters, Celcius/Fahrenheit, and PSI/KPA. ScanGauge II will automatically convert when changing units of measure. If you choose Km and Liters, fuel economy is reported as liters/100Km (LHK). All other units of measure are as they are observed.
