In Canada all speed linmit signs were changed to km/h over the Labour Day week end of 1977 by the simple process of slapping a decal over the existing signs. At the same time all new cars sold in Canada from that date had to have metric speedometers. Weather reporting went metric in April 1975. News reporting is metric which involves Canadian Press translating Associated Press despatches from inch/pound to metric. Quantities of grain are recorded in kilograms instead of bushels, a considerable saving of time from the old way of converting mass into volume units (bushels).
