how many ounces are in a gal
Best Answer: 128 oz in a gallon. 8 oz in a cup. 4 cups in a quart == 32 oz in a quart. 4 quarts in a gallon == 128 oz in a gallon. Strangely enough I don't think they teach this in all schools anymore. I'm not being sarcastic. This is actually not taught in at least some schools.
