📐 Water Intake Calculator Formula

Daily Water (ml) = (Weight in kg * 33) + (Exercise Minutes / 30) * 350
  • Base Need: 33 ml of water per kilogram of body weight
  • Exercise Need: Additional 350 ml for every 30 minutes of exercise

📝 Example

If you weigh 70 kg and exercise for 60 minutes: Base need = 70 * 33 = 2,310 ml. Exercise need = (60 / 30) * 350 = 700 ml. Total daily requirement = 3,010 ml (or about 3 Liters / 12 glasses).
