Someone posted recently an article from a newspaper in the prairie provinces arguing against the current Canadian metric muddle and recommending going back to Imperial or completely forward to metric. (Hard for me to see how they can go back given all the current investment in metric, like speed limit and distance signs, and the fact that the last hold-out, the USA, is inching -- yes, that's deliberate on my part --- towards conversion.)
I saw this quite clearly on the Science Channel last night on a program that talked about monster trucks. (No, not what you see at the speedway on Saturday night, but the huge multi-million dollar trucks that are used in mining, etc.) They shot the program in Canada, and the engineers and other folks interviewed kept bouncing around from metric to Imperial. The pattern I thought I discerned was that they used metric for short distances (metres) , liquid quantities (litres), and temperature (degrees Celsius) and Imperial for longer distances (miles). Come to think of it, that sounds a lot like what most Brits seem to be doing these days, n'est-ce pas? Don't they have a muddle there, too?? ;-) Still, there miles ahead of US! (Still deliberate ... )
