Daily water intake calculator
This tool estimates how much water you need each day by factoring in weight, activity level, and climate.
The Water Intake Calculator offers an approximation, not a precise measurement. Its accuracy can vary—especially for people of certain racial or ethnic backgrounds, those with high muscle mass, pregnant or lactating women, children, older adults, and individuals with specific medical conditions. Use it as one data point rather than a stand-alone diagnostic guide, and discuss your results with a physician for personalized advice.
