A Water Intake Calculator is an online tool that helps you determine how much water you should drink based on your body weight, activity level, and climate. It uses a simple formula to calculate your daily water intake recommendation and helps you track your daily water intake.

How does a Water Intake Calculator work?
Jump Tag Icon

Note that this formula is just a general guideline and may vary depending on individual factors such as activity level, climate, and overall health. It's best to consult with a healthcare professional if you have any concerns.
