 ** multiplier indicates how often a quantity unit is used, i.e. 6 (25 cl bottles). This is a number.

 ** unit is the element the numbers and sizes refer to, i.e. pot, bottle, sack, etc.
-Some remarks:
-* not all 4 elements are always specified, eg 250 g means 1*250 g for the entire product
-* sometimes more than one quantity is specified, e.g. 250 g (5x50 g) might mean 1x250g for the entire product OR 5 50g pots
-* there are exceptions, such as multiple multipliers.
-* naturally users do not use this formal approach, but most quantities can be translated to this approach.
