[USMA:8968] RE: gram precision

[Gregory. Peterson & Tammy. Booth Peterson]

I think it's safe to say that we need the implied millilitre and gram precision
while we still have products packaged in soft converted containers.

If a consumer sees "454 g" or "355 mL" on a container and compares it to a
product of the same price that says "450 g" or "350 mL" the consumer will
choose the larger mass or volume even if the actual package contents could vary
by as much as �10 g or �10 ml.

I know that in Canada we have tolerance limits for packagaing. Similar
regulations must exist in the United States and elsewhere.

Maybe when we move to hard metric packaging we can start using dag, hg, cl, dl,
etc.

At least, if we're going to use ml and g in North America then we should take
advantage of it and package products in quantities such as: "333 ml", "666 g"
in addition to 30, 50, 100, 150,  200, 250, 300, 500, 600, 750, and 1000.
