Water Intake Calculator

Calculate your daily water intake needs based on your weight, activity level, and climate.

This calculator uses a common guideline of around 30 ml of water per kilogram of body weight and adjusts it based on your activity level and climate. Individual needs may vary.

Enter your body weight in kilograms. If you know your weight in pounds, divide it by 2.2 to convert.

Choose the option that best matches how active you are on a typical day.

Hot and humid environments usually require more water intake.
