If they are comfortable calculating the sample mean and standard deviation and the t-score of a student-t test, I'm sure the conversion of the Customary declaration to metric and comparing them is pretty trivial.

The typical 12 ounce soda can is labeled as 355 mL, which is more then 12 ounces so technically the metric declaration becomes the primary standard. The converted numbers should always be rounded up that metric then is the primary standard. It must be a living hell for an inspector to know what amount to test to. Jerry From: John M..

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)
