    Shouldn't that be 5:2?

    Per a calculator provided by Bing,

    5KM = 3.10685596Miles

    so, no, 5:3 is correct.

    Depending, of course, on your definition of "mile".

    5:2 is close to the centimeter/inch ratio

    Rough approximation, 100km = 60miles, so 10:6 or 5:3.
    Another rough approximation, five centimeters is about 2 inches (5:2).

    Either side of the middle...

    1 statute mile (by definition) is exactly 1609.344 meters. Thus, 1
    meter per second is approximately sqrt(5) miles per hour.

    The survey mile was based on the old definition of the foot, which (confusingly) sets 12 meters at exactly 39.37 feet.

    (Note that both of these definitions use the meter as the base!)

    The usual rule-of-thumb conversion is that 5 mi ~= 8 km, which is good
    enough to two significant figures. (You'll note that 8/5 is exactly
    1.6, which is 0.58% too small.)
