According to this government report it would cost less than a million to convert the countries road signs to metric. A pittence when you consider its a one off payment for a country wide project. We are sluggeshly crawling towards metricisation despite the next generation being solely educated in metric mesurements. We currently have this bizare hybrid system including using miles to the gallon despite dealing in litres in at the pump. Is it time to end this madness? I think you can guess my view.
