                                According to the U.S. National Academies of Sciences, Engineering, and Medicine, the average daily fluid intake is approximately 15.5 cups (3.7 liters) for men and 11.5 cups (2.7 liters) for women. Based on a standard 16.9 oz (500 ml) bottle, this translates to about 7-8 bottles for men and 5-6 bottles for women, though the normal amount of water bottles to drink in a day is highly personal.
