The content of HealthCalculators — including all calculators, articles and supporting text — is provided strictly for informational and educational purposes only. While we use widely cited published formulas and review content for plain-language accuracy, calculators cannot account for individual variations, undiagnosed medical conditions, measurement errors, or special populations.

Not medical advice

HealthCalculators does not provide medical advice, diagnosis or treatment. Use of this Site does not create a doctor-patient, dietitian-client or any other professional relationship. Always seek the advice of your physician or other qualified healthcare provider with any questions you may have regarding a medical condition or before starting a new diet, supplement or exercise program. Never disregard professional medical advice or delay seeking it because of something you have read on this Site.

BAC calculator

The Blood Alcohol Content estimator is for educational purposes only. Never use it to determine your fitness to drive or operate machinery. Many factors that affect actual BAC are not modelled, and legal limits and alcohol metabolism vary widely.

Pregnancy and fertility tools

Due-date, conception, ovulation, period, IVF and weight-gain calculators provide estimates only. They cannot replace ultrasound dating or assessment by your obstetrician, midwife or fertility specialist. Cycle length and ovulation timing vary from person to person and from month to month.

Children

Adult BMI categories should not be used for children. Pediatric measurements use age- and sex-specific percentiles that are not implemented on this Site.

Third-party links and advertising

The Site may include links to third-party websites and may display advertising provided by Google AdSense and other partners. We do not endorse and are not responsible for the content, accuracy, claims or privacy practices of those third parties.

No warranty

While we strive for accuracy, results may contain errors and the Site is provided on an "as is" basis without any warranty. Use of this Site and any calculator on it is entirely at your own risk.

Reporting an error

If you believe a calculator or article is inaccurate or out of date, please write to info@healthcalculators.pro with the page URL and a brief explanation. We review every report.
