How do you measure? Metric, imperial, or both?

I saw this notice last week and was a bit puzzled.

In theory Canada has adopted metric measurement. In some areas, road distances and temperature, metric units are used consistently.

But this notice is an example of one of the things that is wrong with metric in Canada. Some things are regularly in metric, other are imperial, and some are in both. In most grocery stores the fruits and vegetables are marked with the price per kilogram and pound.

Australia changed to metric about the same time as Canada, but made a clean break. This made the transition much easier. But Canada is blessed/cursed bu its proximity to the United States. And for virtually all consumer products the units of measurement still imperial. (Think Quarter Pounder etc.)

I do find it ironic that there are few areas where metric measurements has entered the popular domain. One of this is the 2-litre softdrink bottle. But apples are still sold by the pound.
