A few of the ingredients can be used as pieces (pcs.) like: chicken egg raw. The major part of the ingredients doesn't offer this option. The suppliers do not provide nutritional data or weight data per piece.
The same applies to all quantities with volume measure like spoons, cups, quarts, etc.
For the correct calculation of the nutritional values and weights it is important to use measurable units by weight like e.g. gram (g), kilogram (kg), Mililiter (ml), liter (l), etc.
