Water Intake Calculator
Estimate your daily water needs based on your weight, activity level and climate.
How this water calculator works
This calculator uses your body weight as a starting point and adds estimated extra water for exercise and warmer climates.
Water needs vary between individuals and can also depend on diet, health, pregnancy, medications and environmental conditions.
Important: This calculator provides a general estimate only
and is not medical advice. People with kidney, heart or other medical
conditions should follow guidance from a qualified healthcare professional.
