KM speedo converted to mph previously read 30k,then continued up to 75k after conversion,does that mean that it has 30k in km and the remaining 45k in m,or is it all in kms.
The reason I ask is that I had an import Honda which read speed in MPH but the oddo was still in km's,something to do with the face on the dial..cheers.

 

depends on how it was converted
if the drive was slowed down ,then the first 30km was in km and the remainder in mph
however if its only the dial (i.e. the numbers ) hanged, then the odo will still be in km
