how many liters of water should we drink
To better determine how much water you need each day, divide your body weight in half. The answer is the approximate number of water ounces you should drink daily. You should drink half of your body weight in ounces. If you weight 200 pounds, you should drink 100 ounces water (3.13 quarts, 2.98 liters or about 10-12 cups of water a day). If you weigh closer to 100 pounds you will need only about 50 ounces of water or about four 12-ounce glasses daily.
