Water Intake Calculator
How to Use
Enter your body weight and activity level to calculate your recommended daily water intake. The base calculation uses 33ml per kg of body weight, with additional allowance for physical activity. Active individuals, those in hot climates, and pregnant or breastfeeding women typically need more. Remember that water from food (fruit, vegetables, soups) counts towards your daily total.
