It is not true to suggest that the 3-4 grams is not legally important. Any gram figure that exceeds 14 ounces will become the legal figure for the average fill assessment and testing. The law notes the higher figure on the label. That is why conversions must be rounded down and not up. I presume that the sweets in question are labelled and filled according to '14 oz'. It is a bit odd that they choose to give 4 significant figures for grams rather than 3.
