Estimate a suggested daily water intake based on body weight and activity level.
How It Works
How Water Intake Calculator Works
A commonly cited baseline is about 33 ml of water per kilogram of body weight per day, which the calculator then scales up for a moderate or active lifestyle, since exercise and sweating increase fluid needs beyond the sedentary baseline.
FAQ
Frequently Asked Questions
Does this account for water from food and other drinks?
No — this estimates total fluid needs; roughly 20% of daily water intake typically comes from food, so treat this as a rough target for combined fluid intake rather than water specifically.
Is more water always better?
No — needs vary by climate, health conditions, and individual physiology, and drinking far beyond what your body needs can actually be harmful in rare cases; this is a general starting estimate, not a personalized medical recommendation.
