   Should speed limits be changed to km/h?

   • In contrast, all UK registered vehicle have speedometers that can display speeds in both km/h and mph. Unlike current speed limits in miles per hour, speed limits in kilometres per hour will be compatible with the speedometers of all vehicles on UK roads. It follows that switching speed limits to km/h would be a major improvement in road safety.

   When did kilometres per hour become a metre?

   • Although the metre was formally defined in 1799, the term "kilometres per hour" did not come into immediate use – the myriametre (10,000 metres) and myriametre per hour were preferred to kilometres and kilometres per hour. In 1802 the term " myriamètres par heure " appeared in French literature. [ 1 ]
