Odoo - How to purchase items in one unit of measure, and sell in a different unit of measure

Odoo makes it easy to sell products in different units of measure than you purchase them in. The feature called "Packaging" is basically a product level unit of measure. This is a powerful feature.

My problem is multi UOM conversion: Product X is a 6/1GL case. Whole case or split 1GL. Product Y is 4/1GL, case or split 1GL. Think I just need to allow UOM category to be displayed with UOM just for back end product set up. Otherwise, if you set up the UOM, the drop down selector will show 2 1GL options to select. But you don’t know if it’s the 6/1GL or 4/1GL.

Hmm.. not quite sure I understand, but try this. Let me know how it goes.
Create separate UOM categories: Create distinct UOM categories for Product X (6/1GL) and Product Y (4/1GL). This will help differentiate between the two products' UOM conversions.
Set up UOMs with appropriate categories: Ensure that each UOM (e.g., 1GL, 6/1GL, 4/1GL) is assigned to its corresponding UOM category. This will help Odoo understand the correct conversion ratios.
Configure UOM conversion ratios: Define the conversion ratios between the UOMs within each category. For example, 1GL = 1/6 of 6/1GL (for Product X) and 1GL = 1/4 of 4/1GL (for Product Y).
Display UOM category in product setup: As you mentioned, allow the UOM category to be displayed in the product setup, so users can identify which product (X or Y) the UOM belongs to.
Customize the UOM dropdown: You may need to customize the UOM dropdown selector to show the UOM category or a descriptive label (e.g., "Product X - 1GL" and "Product Y - 1GL") to avoid confusion between the two 1GL options.
