To get the answer, you first need to understand the capacity of a gallon. A gallon equals to 3.8 liter, 4 quarts or 128 oz. It means there should be about 16 glasses of water in a gallon. It also implies that when someone says you should drink eight 8-ounces of glasses of water a day, it's not like drinking a gallon of water. Do You Really Need to Drink a Gallon of Water a Day? Actually, you really needn't drink that much. As per the Institute of Medicine, men should consume 125 ounces of water every day â it's about 3.7 liters and equals a gallon. Women, on the other hand, should consume at least 91 ounces or 2.7 liters of water daily. Since about 25% of water your body needs comes from the food you eat, men need to drink thirteen 8-ounce cups of water daily and women should aim to drink about nine 8-ounce cups of water a day.
