I am a Canadian who spent 8 years overseas, in countries where only metric was used. I still use inches in my sewing room, because that is how most of the patterns are written and how quilting rulers are marked. But I buy fabric by the meter--which is just shy of 4 inches longer than a yard.
Considering that Canada has used the metric system for 50 odd years, I find it inconceivable that grocery stores still advertise meat and produce prices per pound (with the metric equivalent in small print) and that cashiers cannot do the conversion math. (1 kilogram=approximately 2.2 pounds Therefore $1.00 per pound=$2.20 per kilogram)
The metric system is based on multiples of 10. It is a very precise way of measuring and weighing. Even Alton Brown talks about grams of ingredients in his Good Eats Reloaded shows.
Mojo11, if you want printable conversion table, just Google 'metric conversion' and you will find a multitude to choose from.
