Although it seems difficult to calculate water requirements according to weight, there is a simple formula that can help make it easier. The formula consists of dividing weight (in pounds) by two. The result is the amount of water your body needs per day in ounces.

Here is an example to make it a little easier to understand:

A person who weighs 116 pounds should divide their weight by 2 which results in 58 ounces. This amount corresponds to approximately 5 glasses of water per day.

Here is the formula, don’t forget it: (body weight in pounds)/(2) = daily requirement of water in ounces.

Special cases

  • When practicing sports or intense physical exercise, experts recommended drinking an additional liter of water for every hour of exercise performed.
  • As we all know, fruits and vegetables contain a lot of water. Therefore, if you don’t have a diet that is rich in these elements, you should drink at least two liters of water per day. Fruits and vegetables, like many other foods, contain a lot of water which should be subtracted from the recommended daily requirements.
