if my Odomoter reads 66103 on dash, is that (66,103 miles) or (6,610.3 miles) on 2009 Chevrolet Cobalt

The car was bought brand new and not driven that much, so i am trying to check mileage correctly

Odometer reading - 066103 = 66,103 miles on car. The 1/10's of a mile are shown in the tripometer below the odometer.
