What is a Water Intake Calculator?
A Water Intake Calculator helps determine how much water you should drink daily based on factors like your weight, age, activity level, and climate.
How much water should I drink per day?
On average, you should drink about 30–35 ml of water per kg of body weight. This varies depending on your health, physical activity, and environment.
Is this Water Intake Calculator accurate?
Yes, it provides a close estimate based on standard hydration guidelines and personalized inputs like body weight and activity levels.
Why is staying hydrated important?
Proper hydration supports digestion, metabolism, brain function, energy levels, and overall health. It also helps regulate body temperature and flush toxins.
Can I rely only on this tool for my daily water intake?
It offers a helpful guideline, but always listen to your body, especially during illness, workouts, or hot weather, when water needs may increase.
Does coffee, tea, or juice count towards daily water intake?
