If one ml of water weighs one gram and one fluid ounce of water weighs one ounce, why are there 28 grams to the once and 29.5 ml to the fluid ounce?

Because 1 fl oz of water doesn't weight exactly 1 oz: it's actually around 1.04 oz.
See, this is why the Imperial system is the stupidest system ever.

1 kg is not 16 oz. 1 lb is 16 oz or 454g. Where as 1 kg weighs 1000g or approximately 2.2 lbs 1 oz wieighs a fraction over 28g or if you round it up 30g. That is why 3 oz weighs approximately 90g

And just to confuse things even more, in US law a fluid ounce is exactly 30ml!

You have entered the realm of "significant figures", and "accuracy". Look up these two terms.
