n Which weighs more: an ounce of bread or an ounce of water? It’s not a silly question, since fluid ounces measure volume, not weight. A gallon of water (128 fluid ounces) weighs about 8 pounds, 5.5 ounces, which works out to a weight of 1.04 ounces for an ounce of water. It can’t be a coincidence, for water at least, that the two measures are nearly identical. If you can explain how the definition of a fluid ounce was developed, please let us know.
