Because this is not a normal forum, there is no way for a new person to read old postings and thus know what was already said. So until the people who run this forum upgrade to a modern forum style then some of you people who have been posting from the beginning will have to tolerate some repeat questions or comments.
Isn't it illegal to claim a soda bottle contains 24 oz or 709 mL if it only contains 23.66 oz or 700 mL? That's cheating.

The error comes from rounding and works like this. Bottle of soda is 700 ml = 23.66 oz = gets rounded to 24 oz Then the 24 oz gets converted back to metric = 709 ml = gets rounded to 710 ml. Somehow the bottle got 10 ml bigger in the back-conversion.

I agree with your point. But if you consider that the metric is changed to imperial, then rounded to make the imperial look user friendly and then later reconverted to metric; the reconverted metric may be different then the original figures. Hence the confusion as to which units may be more correct, even though both can be wrong to a degree. Does this make sense? Jerry Dear Jerry, I understand the point you are making. Perhaps my grandmother put it rather well when she said: 'Oh, what a wicked web we weave, when first we practice to deceive'.

You might like to listen to the streaming of the fire emergency radio radio station at http://www.abc.net.au/melbourne for a few minutes where all official measuring is reported in metric units - only. Dear Martin and Harry, Thanks for your thoughts. It will be a hard time for us as we recover from this disaster.

I think there are some conversion errors so I'm not sure which is correct, the English or the metric.
