Water Intake Calculator — Description
The Water Intake Calculator estimates a daily hydration target based on body weight, activity level, exercise duration, climate, and optional pregnancy or breastfeeding adjustments. It shows the recommended intake in liters, milliliters, fluid ounces, and cups.
This tool is useful for general wellness, fitness tracking, and daily hydration planning. Because real hydration needs vary from person to person, this calculator should be used as a practical estimate rather than a strict medical prescription.
