Optionally seperate nutritional values for 100g VS 100 ml.

[Kezxo]

Is your feature request related to a problem? Please describe.
Some liquid products are lighter than 100g per 100ml so treating them as one of the same can be misleading. I have come across ice cream that show separate nutritional values for 100g vs 100ml so I was confused which numbers I should enter.

Describe the solution you'd like
Let the user pick between 100g, 100ml or maybe both at once. I guess both should still be the default.

Describe alternatives you've considered
Leaving it like it is but that can be confusing or misleading, products might seem more or less healthy than they actually are.

Additional context
Here is an example of a product that shows both nutritional values for 100ml and 100g: https://world.openfoodfacts.org/product/7310290006686/
Note how the numbers almost double when going from 100 ml to 100 g.
