Just came back from a US trip and found that when I drove in a 60 mph zone, the TomTom converted the speed to 95 kph. Why is it converting to 95 kph when the standard norm is 100 kph?

    In fact, the true conversion of 60 mph to kph is 96.56064 kph. So, close enough.

    That may be true but in North America 60 mph is considered as 100 kph. Also when I first got the TomTom, 60 mph converted to 100 mph.

    Maybe a map/software update includes different code for conversions of speeds.
