You are correct on how the net contents would be tested in the US; the regulations caution not to round the converted value up.

Metric is already the primary system used for trade measurement throughout the EU (apart from the pint for draught beer & doorstep milk in a few places) In the EU, packages are required to comply with the requirements relating to their metric marking. A package marked "454 g 1 lb" would be tested to 454 g. A package marked "453 g 1 lb" would be tested to 453 g (ie the metric is always primary) As far as I am aware, US packages marked with the same indications would be tested to 454 g & to 1 lb respectively (ie to the larger of the 2 contents declarations)
