How Do I Calculate My Daily Water Intake?

You can easily calculate your daily water intake based on your weight with the following formula:

The formula for daily water intake:

For male:

Weight (lbs) * 0.5

Example:

For a male: How much water intake do I need if my weight is 158 lbs?

So, let’s put the value for weight into the above equation:

158 lbs * 0.5

So, the water intake for a male weighing 158 lbs is 79 oz.

Also, if the weather is warm, you need to add 10%. Here are the steps:

  • 79 * 10%
  • 79 * (10/100)
  • 7.9
  • Add 7.9 to 79 oz
  • The ideal hydration requirement in warm weather is 86.9 oz.

For Female:

Weight (lbs) * 0.45

Example:

For female: How much should I drink, if my weight is 145 (lbs)?

So, simply add the values into the above formula equation:

145 (lbs) * 0.45

So, the daily water intake for a female with 145 (lbs) is 65.3 oz.

If the weather is warm, then follow the same steps mentioned above for males.
