Did you look closely at the label in the picture?  It wasn’t 1 L, but 999 mL.  
1 L was converted to 33.8 fl oz and that was backconverted to 999 mL.  

Since the label is in error, who do you complain to so hopefully the label will 
be fixed?

They have to leave the 1 L, because the FPLA requires DUAL labelling. Neither 
the metric only nor Customary alone is sufficient under the current law.  Your 
hypothetical is illegal in the US.

  Hi:


  Suppose someone takes a 1 liter bottle of Safflower seed oil and  converts 
the label info to legacy units for sale in the US.

  Then later, someone else wants to put on the label metric units, uses the 
legacy info and converts it back resulting in a round off error.

  See the attached picture.


  Also, in the discussion about "er" vs "re" endings on units of measure, you 
remember the legacy unit of land area: acre.  It is defined as 43560 legacy 
square feet.  Anyway, should it be spelled "acer".

  Just a tidbit.
