Don Burke:The product packaging seems to be slowly migrating. I have been buying soda in two liter bottles for some time now.
This is true... But do you buy dog food in 50Lb bags, or 22.7 KG bags?
Some switches would be easy... like for me... My scale I flick a switch, and I go from Ounces to Grams.
In addition to the obvious economic impact of switching... Let's also think about some of the less educated areas in this country. I bet there are many people who don't know how many ounces in a pound, or how many cups in a pint, or that 20 degrees is a comfortable temperature. Granted that metric is much easier to use... I don't see it happening here.
As previously stated in this post... I can see England changing over, even though the imperial measurement system is often called the English system... But I think that is more a factor of the "european community" and that England is on their own system.
