1 Multiply by 2/3: Next you want to multiple your weight by 2/3 (or 67%) to determine how much water to drink daily. 2  For example, if you weighed 175 pounds you would multiple that by 2/3 and learn you should be drinking about 117 ounces of water every day.
To find out how much water you should be drinking, divide your body weight by 2, and that will be how much water you should drink in ounces. For example, someone weighing 120 â¦ pounds would need 60 ounces of water each day since 120 divided by 2 is 60.ne school recommends a daily water intake based on a person's weight in pounds. Divide the number of pounds in â¦ half-this is how many fluid ounces of water you should consume each day. So, for a 110 pound person, this would mean 55 fluid ounces of water per day.
