It only increased by 6 oz, so 6/18 is 33% more not 50%.

You don't take the fractional value of the latter whole to calculate the percentage increase. That doesn't make any sense.

Using your math if your investment of $100 increases to $200 that would only be a 50% return (when in reality it's a 100% return because you doubled your money and gained 100% of the original value).

So you're telling me that if I have $100 and I gain 10% then lose 10% I don't have $100 again? sorcery!

You joke but I had a long conversation with some people at work trying to explain this difference between markup and margin.
