Clearer verbiage for Edit Product field (Affects US users)

[zanovis]

What

• This issue is to request a more instructive name for the Quantity field for US products.

Example

The current 'Quantity' field is for the product's total mass (if solid) or volume (if liquid). Quantity intuitively seems like the discrete amount of the products in the package, so if you have candy with 2 pieces, quantity would be '2 pieces'.

In the US, we call this value 'Net Weight' and have 'oz'/'g'/'fl oz'/'mL'.

Current edit product field name: 'Quantity' (API: product_quantity)

Proposed US-based edit product field name: 'Net Weight/Volume' (I understand 'weight' is a misnomer, since products display the value in 'oz' AND 'g', but this would make it match US product labels 1:1)

To Reproduce

View a product's edit page

Expected behavior

A US user expects to see field titles that match the product's field names on the label.

Additional context

I believe this change would make users more likely to enter this data and it would also improve the reliability of this data because there would be less confusion about if this is 'serving size' vs 'total mass'.

The quantity field does not to seem to be processed and normalised. I could not find a normalised entry in the json.

It shoudl also be possible to add the number of servings in this field as well (some extra parsing).

@aleene The "quantity" field is a text field, it is normalized in the "product_quantity" field (which is either in g or in ml).
e.g. https://world.openfoodfacts.org/api/v3/product/3033490004521?fields=quantity,product_quantity

product_quantity: "500",
quantity: "500 g (4 × 125 g)"

@zanovis We could rename the "Quantity" field in "Quantity (Net weight or volume)". Making the name specific to countries would be difficult to maintain.

@stephanegigandet thanks, not sure why I missed that. Might the field be left out sometimes?
