I just purchased the 3 pak of the organic ground beef. The label reads 21.44ozs. per pak. When I weighed each pak the weight was only 19.5 ozs. That is 5.8 ozs. short for the entire 3 paks. At $13.99/# the customer is shorted $1.26. How can Costco get away with that and why isn't someone regulating the packaging???
Maybe a former customer.

Let me guess, this package was labeled something like 600 grams?
Your scale is calibrated to equate 30g to equal 1 ounce. This is incorrect, although very common. 600/30 = 20, which is about what you weighed. (I'd ignore the 1/2 ounce difference unless you have a very, precise scale).
An ounce is 28.3495231 grams. This is sometimes rounded up to 29 or 30, or down to 28. All of them are imprecise.
If you divide 600 / 28 you get 21.42, which is about what they labeled.
Summary: the US needs to start using metric and join the modern era!
