Is 8 oz the same as 8 fl oz?
No. Fluid ounces measure volume, not weight. 8 fl oz of water weighs about 236.6 g because water is roughly 1 g/mL. But 8 fl oz of honey would weigh much more.
How many ounces is 200 grams?
200 ÷ 28.3495 = 7.05 oz. Just over 7 ounces.
What does 1 oz look like?
About 6 teaspoons of sugar, or the weight of a standard envelope with a few sheets of paper inside.
