Water Intake Calculator
Find your recommended daily water intake based on body weight, activity level and climate.
What is Water Intake?
Water needs depend on body size, activity, climate, and health. The estimate balances baseline needs (~33 mL/kg) and exercise-related losses.
How is it calculated?
Water (mL/day) = (weight×33 + activity bonus) × climate factor.
