According to experts, the solution is as simple as
1. Take your weight (in pounds) and divide that by 2.2.
2. Multiply that number depending on your age.
- If you’re younger than 30, multiply by 40.
- If you’re between 30 and 55, multiply by 35.
- If you’re older than 55, multiply by 30.
3. Divide that sum by 28.3.
4. Your total is how many ounces of water you should drink each day. Divide that number by 8 to see your result in cups.
