With this advice there is a tip I recall from my time overseas.  If you want to convert kilometers to miles on the fly you multiply kilometers by 6 and drop the last digit.  It isn't exact by any means but gives a fairly close approximation without having to use a conversion calculator.  But unless you are driving a car that doesn't have km/h on the speedometer it probably doesn't have much use outside of curiosity and just having a general idea what the kilometers are in miles.  Or I suppose if someone bet you a sum of money that you could not run say 10 kilometers and you wanted to know if you could do it.
