Is Water Intake medically accurate?

Water Intake uses standard clinical formulas — BMI = weight (kg) / height (m)², BMR uses the Mifflin-St Jeor equation, and body-fat estimates use the U.S. Navy method. The math is correct, but these formulas are population averages and don't account for muscle mass, ethnicity, or medical conditions.

Should I make health decisions based on Water Intake?

No — this is an educational tool, not medical advice. Use the result as a starting point for a conversation with your doctor or a registered dietitian, especially before starting a new diet, workout regime, or supplement.

Does Water Intake save my health data?

No. Everything runs client-side in your browser — weight, height, age, sex, and any measurements you enter are never uploaded, logged, or shared. Reload the page and it's all cleared.

Does the tool support metric and imperial units?

Yes. Water Intake accepts kilograms/centimetres as well as pounds/feet-inches, and toggles between them without recomputing manually. Conversions are handled internally.

Why do BMI or BMR numbers differ between calculators online?

Different sites use different equations — Harris-Benedict vs. Mifflin-St Jeor for BMR, or older BMI cutoffs. Water Intake uses the currently-recommended formulas and shows the equation used so you can verify.

Is Water Intake free and accessible?

Yes — completely free, no signup, works on any device (mobile, tablet, desktop) with a modern browser. Fully keyboard-navigable and screen-reader friendly.
