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.
For people who are above / below average weight see equation for how much water you should drink in a day: 1/2 to 2/3 of your body weight (lbs) is how many ounces of water you should drink at a minimum in a 24 hour period-NEVER all at once.
