And don't forget that the metre was redefined in 1983. If specifying a  
speed in km/h, you should ascertain the age of the sign to see whether  
it's 50,000 * one ten-millionth of the distance from the Equator to  
the North Pole via Paris, or the distance travelled by light in an  
absolute vacuum in 50,000 299,792,458ths of a second.
