== Quantities ==

Collecting quantity isn't so simple:
 +
* we can see various units
 +
* we can see various ways of dealing with net weight and drained weight
 +
* sometimes portions are well specified and sometimes not
 +
* we can see many ways of ordering printed data on the packages

The ℮ sign (for "[https://en.wikipedia.org/wiki/Estimated_sign estimated sign]") is used in Europe and other countries, at least Australia: https://www.industry.gov.au/sites/default/files/2019-04/guide-to-the-average-quantity-system.pdf (p. 12)

It seems to refer to the Average Quantity System (AQS) which is in use in Australia, Canada, European Union, India, Japan, New Zealand, South Africa and Switzerland -- source: https://www.sfa.gov.sg/docs/default-source/tools-and-resources/resources-for-businesses/avabriefingonaqsslides1 (slide 3).

For the moment, the best is to enter the data as it is printed on the product.

This formula should be valid for each container/subcontainer/subsubcontainer level, but should reflect the entire package. So one has to add multipliers and brackets where appropriate.
    
For example:
