How many grams are in a fluid ounce?

Question

How many grams are in a fluid ounce?

Answer 1

It depends

A fluid ounce is a measure of volume, and a gram is a measure of weight. It's like asking how much does a person weigh who is 6 feet tall. It depends!

A dry ounce is a measure of weight, however. In one dry ounce, there are 28.35 grams, but this is not a "fluid ounce" (volume). To know the weight of one fluid ounce, we would need to know the density of the substance so we could derive the weight per given volume (grams per fluid ounce) or volume per given weight (fluid ounces per gram)

Answer 2

28.35

Answer 3

29.57 grams in a US liquid ounce(water).  http://www.onlineconversion.com/weight_v...
