Frequently Asked Questions
How accurate are these health calculators?
Our calculators use standard medical formulas and are accurate for general population estimates. However, individual health varies significantly based on genetics, body composition, and medical history.
Should I rely solely on BMI for health assessment?
No, BMI is just one health indicator. It doesn't account for muscle mass, bone density, or body composition. Consider it alongside other health metrics and professional guidance.
Can I use these calculators for medical purposes?
These tools are for informational and educational purposes only. They should never replace professional medical advice, diagnosis, or treatment from qualified healthcare providers.
Do you store my health data or personal information?
No, all calculations are performed locally in your browser. We don't store, collect, or transmit any personal health information or calculation data.
Are these calculators suitable for children or elderly?
Standard BMI calculations may not be appropriate for children under 18 or adults over 65. Consult pediatricians or geriatricians for age-appropriate assessments.
How often should I track my health metrics?
Weekly or bi-weekly tracking is usually sufficient for most people. Daily fluctuations are normal and shouldn't cause concern. Focus on long-term trends.
