Yes, we use the metric system in Canada. It is logical and simple. Water freezing at 0, boiling at 100, 1 milliliter of water weights 1 gram, one liter or cubic decimeter is 1 kilo, 1 cubic meter or 1000 liters weight a metric ton (1000 kg). But we still use the old system for the description of personal height (feet and inches) and sometimes for fuel consumption. Everybody here knows exactly how warm is 25 c and how heavy is a 60 kph wind. But it is still more simple, especially for older people, to use pounds and feet measures most of the time. I'm not sure but I think USA is the only country in the world who does not use the metric system. It takes time to convert, and sometimes errors happen when we mix the two systems, like that space vessel crashed on Mars (metric and imperial navigation data mixed without conversion /images/graemlins/rolleyes.gif)
