Always use the "Metric" system, that is Grams, and Liters.
Your regulatory system will heavily use these numbers and all items will be treated uniquely. So, pay good attention to these identifiers when scanning, updating or modifying items.
It sounds counter-intuitive but slowing down, double checking the plan before proceeding and checking your work right after can save a lot of headache. If you rush through a process and make a mistake these regulatory systems make it difficult to correct. Better to delay a process by a few hours and do it correctly than to rush the process and have to spend a bunch of time undoing a mess.
