❓ FAQ
How much water should I drink per day?
The general guideline is 35ml per kg of body weight. A 70kg person needs about 2.45L/day. Activity level and climate increase needs further. Our free water intake calculator personalizes this recommendation based on your specific factors.
How do I calculate my daily water intake online?
Enter your weight, select your activity level (sedentary to very active), and choose your climate. Our water intake calculator instantly shows your recommended daily intake in ml, liters, cups (200ml), 500ml bottles, and 2L bottles.
Does exercise increase how much water I need?
Yes significantly. Light activity adds about 15% to your base water needs. Moderate activity adds 30%. Very active individuals may need 50-70% more than sedentary baseline. Our calculator applies the correct multiplier automatically based on your activity selection.
