or

Water Intake = Weight (kilograms) × 2.2 × 0.5

  • The number represents the recommended amount of water you should drink daily in ounces.
  • This is a general guideline and may not account for all individual factors.
  • You may need to adjust your water intake based on your activity level, climate, and overall health.

For example, if you weigh 150 pounds, the calculator will recommend about 75 ounces of water per day. This is a starting point, and you may need to drink more or less depending on your specific needs.
