for the record, this country has 2 forms of measurement.
 

Now we're really stepping away from radio talk and crawling our way deep into grocery store talk.
If you're running a business and you want to sell as much food as possible what do you want the eyes to see?
A seemingly low price? Or a seemingly HIGH price? 
Showing something per 100g looks great on the eye, but also, showing something in LBS ALWAYS looks better to the eye than a sign with the price in KGs. 
So, that being said, this is indeed one main reason why metric alone never caught on as strictly the only choice in Canada for measurement.
