What this site is
Water Intake Calculator Free is an independent website that gives general information and simple estimates about daily water intake for healthy adults. It is not medical advice, and it does not replace advice from a doctor, midwife, dietitian or other qualified health professional.
The numbers on this site come from common rules of thumb and plain arithmetic. They are rough estimates. Your own needs can be higher or lower, depending on your body, your activity, the weather, your health and the medicines you take.
Who should ask a doctor
Talk to your doctor before you change how much you drink if you are pregnant or breastfeeding, have kidney or heart conditions, take medication that affects fluids, or have been told to limit or increase fluids. Drinking much more than your body can handle, especially in a short time, can be harmful.
Children
This site has no calculation for children. If you are looking after a child, ask a pediatrician how much they should drink.
Use at your own risk
If you feel unwell, or think you have a medical problem, contact a doctor or your local emergency number. Do not wait for a website.
We make no health promises. We do not claim that any amount of water will lead to any health result. You use this site at your own risk. If you have a question about the site, see the Contact page.
