I couldn't buy my 2L Coke Zero today as the store was out. So I looked at
other sizes that were in stock. They had a twin pack of 50 fl oz bottles which
was close to the same unit price.
When I looked more carefully at home, each bottle was labelled 50 FL OZ, 1.6
QT, 1.48 L.
Except 50 fl oz ISN'T 1.6 QT, it is 1.56 QT, and they are not allowed to round
up as it overstates the contents.
I assume the contents are really 1.48 L, which is 50.05 fl oz, and rounding
down to 50 is acceptable.
If the fill were really 1.6 QT, that would be 51.2 FL OZ (two digit, 51 FL OZ
would be required), and 1.514 L (3 digit, 1.51 L). It is OK to round down but
not to mis-state at the level of precision chosen (or required).
I belabor the point only because FMI claims that a much simpler metric-only
label would be absolutely impossible to manage. If they love the status quo so
much, they should make sure their members rigorously obey the current law.
I also question whether we need a 50 FL OZ size, when 1L, 1.5 L, 2L exist..
Are soda manufacturers trying to sneak back to Customary?
