How much does 9 oz of water weigh in grams?

Answer 1

A gallon of water weighs approximately 9 pounds. There are 128 (fluid) ounces in a gallon. There are 16 ounces in a pound. So, let's do the math. 9 x 16 = 144 ounces in nine pounds in one gallon of water. 144/128 = 1.125 ounces for each fluid ounce of water. 1.125 x 9 = 10.125 ounces. So! Nine fluid ounces of water weighs approximately 10.125 or 10 & 1/8th ounces. Probably not how my math teachers would have preferred I do that, but what can one expect from an English major?

Answer 2

A gram is a measure of mass, not weight.
